Thoughts on successful postdoc-ing

Unlike grad school, postdoc positions start and end without much fanfare. If grad students are apprentices, postdocs are the journeymen/women of the trade. (Wikipedia defines journeymen as… “considered competent and authorized to work in that field as a fully qualified employee… [but] they are not yet able to work as a self-employed master craftsman.”) Though short compared to a PhD, postdoc jobs are an important stepping stone towards a 'real' job, be that another postdoc, or a position inside or outside of academia. There’s less advice out there about being successful as a postdoc, and often you are on your own to figure things out. I’m finishing a first postdoc this week, and moving on to a second one, and while I think the last 2 years worked out well, they took their own, unexpected path. Some of this is good advice that I was given, some comes from experience or observation, some I even manage to follow :-) *

Choose carefully. If you have some choice, be strategic in choosing a postdoc job. Decide what the position is going to accomplish for you: that may be expanding your skill set, such as by learning a new experimental system or additional analytical techniques; improving your current skills by working with an expert; being involved in high profile research; or being in a certain locale for various reasons. Beware projects too far from your current skill set – the risk is that the learning curve may be so steep that you will be barely competent at the end, and have little to show for your time. Of course, you might decide to use a postdoc to pursue interdisciplinary work, or move away from your dissertation work, in which case this is a risk worth taking.

Because postdocs are short, it may seem as though having a good fit with your supervisor is less important. Don’t assume that your new supervisor be broadly similar in approach to your previous supervisor (or an improvement). Mismatched expectations between supervisors and postdocs seem pretty common and it’s important to get an understanding of what your role is beforehand. The variation in expectations from supervisor to supervisor is huge - from those that require time sheets and expect strict hours, to those that give you total autonomy. Does your supervisor see postdocs as colleagues? 9-5 employees? Advanced students? Lab managers? Talk to friends, colleagues, and students. This may depend on the source of funding as well - will you be working on a specific existing project with specific timelines (common in the US where many postdocs are funded off of NSF grants), or are you funded by a fellowship and therefore more independent?

Get to know your neighbours. Once you’ve chosen and started your postdoc, the most important thing to do is to establish connections in your lab and department immediately. I cannot emphasize this enough. Don’t wait to settle in, or get on top of some papers, or hope people in the hallway will introduce themselves. Postdoc positions are short, and in many departments postdocs are isolated, not students but not really faculty. This can lead to feelings of disconnection, loneliness, and frustration. Seek out the other postdocs - join or organize postdoc social events, go to lab meetings and journal clubs, get the department to maintain an active postdoc email list. Not only will this give you a sense of belonging, but now you have people to talk to (and sometimes rant to), with whom to navigate administrative issues, and potential collaborators. Postdocs are an invaluable resource for job applications as well: they usually have the most up-to-date experience on the job market, and can provide great feedback on job applications and practice job talks. For example, the postdocs in my current department built an exhaustive list of potential questions asked during academic interviews, and shared interview horror stories over drinks.

Mental health and life balance. Postdocs don’t get the kinder, gentler approach sometimes given to grad students and people expect you to stand on your own. This can reignite imposter syndrome. There is no easy solution to this, but some combination of taking care of yourself, working on that mythical thick skin, and highlighting the positive events in your life can help.

Time management continues to become more important, at least for me. More than in grad school, you have to actively decide how much work you want to be doing. There is always something that you *could* be working on, so start scheduling when things will get done based on priority, energy, etc, is important. In addition, people start inviting you to things or asking for you input on projects. Learn to say no. Be strategic about your time management – it’s flattering to wanted, but time is limited and not all invitations are of equal value towards your specific goals.

Practice professional networking. On the other hand, don’t say no to everything: networking and the opportunities it creates are very helpful. Focus on the professional areas that are of interest to you, but consider joining and being active in ESA sections (including the Early Career section) or other relevant organizations; organize workshops or symposia at conferences; host invited speakers. If your department hosts an external seminar series, take advantage (nicely!) of the revolving cast of scientists. They are a great way to make connections with people whose work you admire, and even speakers you have less in common with are great practice for networking skills. From experience, if you have breakfast with a different visiting speaker every week, you will quickly improve your description of your research and your ability to keep a conversation going (also, you will become an expert on your city’s breakfast places). These are helpful skills to have for faculty interviews, for talking to the media and press, even for telling your family what you do.

Take initiative. You are your own advocate now. If you wish you could learn something, or be invited to a working group, or get teaching experience, look into making it happen yourself. This may include organizing working groups (many provide competitive funding, for example, iDiv/sDiv, CIEE (Canada), the new NCEAS, SESYNC), applying for small grants and other project funding on your own, recruiting undergraduates and mentoring them, organizing or co-teaching courses.

Similarly, don’t stop learning new things. Inertia gets higher the less time you have, and it can be hard find the time to pick up the next skill.

Publish. Focus on publishing (if you are interested in academic jobs)– this may be obvious, but publishing is more important than ever as a postdoc. You need to show that you are independently able to produce work after leaving your PhD lab. This counters the ‘maybe they just had a good supervisor’ concern. It can be hard to find time to work on both current and past projects, but try to. From experience (and illustrated by the periodic emails from my PhD supervisor), the longer your dissertation chapters sit around, the less likely they are to ever be published…

Know what your dream job is, and apply for it if you see it. Be willing to move on if something better comes up. Postdocs usually have to think in the short-term, because most funding is in 1-2 year increments. So keep an eye on new sources of funding/positions. Make decisions based on your needs (be they career-related, family-related, whatever): it’s easy to feel guilty moving on from one unfinished position to another, but the reality is that postdocs are temporary and fleeting.

I was told to start applying for jobs as early as I felt reasonably qualified. The logic was that the best practice for job interviews is doing actual job interviews, and further, it is better to fail when it doesn’t matter, rather than when it is your dream job.

well, sort of...

*Obviously nothing is one-size-fits all, and this is mostly aimed at people who plan to apply for faculty jobs eventually. Other advice, especially for non-academic tracks, would be welcome in the comments!

Debating limits on diversity in class

I wrote a while ago about the debate on whether global diversity has ecological limits, based on two papers from Harmon and Harrison, and Rabosky and Hurlbert. This was in turn based on a debate from the ASN meeting (aside: there should be more formal debates at conferences). I decided to try replicating this debate in the Advanced Ecology class I'm teaching with Kendi Davies, and I was pleasantly impressed with the outcome. The class is mostly upper year students and small (~25 people), and the focus is on reading the primary literature and exploring key topics in ecology using active learning techniques (e.g. 1, 2). Since we're reading about patterns and processes of diversity through space and time, the debate topic was fitting.

The debate was split over two classes - in the first, students were split into two groups and they prepared their opening and closing statements and their supporting arguments. I've tried having students use Google documents and slides for these kind of group collaborative activities, and it seems to work well. (This is in part because there are 'lender laptops' available from the department's IT, which means that all students can participate, even without owning a personal laptop). What is great about Google docs is that when anyone adds or removes or edits text, the other members of the group can see it in real time, which seems to encourage more students to be actively involved than if, say, a single student is taking notes. Each group decided who would present the opening statement, each supporting argument, the rebuttal statement, and the closing statement, and who would take notes and prep the rebuttal.

To raise the stakes a bit, the winning team would get a pass on one homework assignment (the other motivator presumably being fear of letting their group down). What impressed me was how engaged students were during prep and during the actual debate. (For example, during prep, students were watching videos on how to debate, and expressed some concerns about espionage by the other teams ;-) ) More seriously, they took the time to understand the arguments presented in the source literature, and went beyond that to integrate support from other primary literature. I think at times students (okay, most of us) can get away with skimming papers for the key points: this rewarded them for reading carefully and thoughtfully.

Current US political debates provided instruction
on what not to do (from cnn.com).

The judges were a few generous postdocs (motivated by the promise of free food), who not only scored the debates, but gave some feedback to the teams. Ironically, the winning team had argued that “Species Diversity Is Dynamic and Unbounded at Local and Continental Scales” (after Harmon and Susan Harrison), but the class was nearly unanimous that they personally felt that there likely were ecological limits on diversity.

What I would do differently next time:

• Plan some redundancy - a couple of people were sick, etc, who had roles in the debate. This left team members scrambling a bit. 
• Group sizes: 12 people is a bit big for a group and makes coordination difficult. It might be possible to have smaller groups and do 2 sets of debates. Or, alternatively, to assign half the class as judges (or press - another prof here uses students as press who have to prepare questions for the debaters).
• Consider not randomly assigning people to groups - it might be better to try to balance teams.
• Public speaking and argument logic - interestingly, most of the students have little experience in constructing convincing and well supported arguments. We talk a lot about hypothesis construction with STEM students, but persuasive speech and writing receive less attention. Things like 'signposting' important points could use more practice.

Pulling a fast one: getting unscientific nonsense into scientific journals. (or, how PLOS ONE f*#ked up)

The basis of all of science is that we can explain the natural world through observation and experiments. Unanswered questions and unsolved riddles are what drive scientists, and with every observation and hypothesis test, we are that much closer to understanding the universe. However, looking to supernatural causes for Earthly patterns is not science and has no place in scientific inquiry. If we relegate knowledge to divine intervention, then we fundamentally lose the ability to explain phenomena and provide solutions to real world problems.

Publishing in science is about leaping over numerous hurdles. You must satisfy the demands of reviewers and Editors, who usually require that methodologies and inferences satisfy strict and ever evolving criteria -science should be advancing. But sometimes people are able to 'game the system' and get junk science into scientific journals. Usually, this happens by improper use of the peer review systems or inventing data, but papers do not normally get into journals while concluding that simple patterns conform to divine intervention.

Such is the case in a recent paper published in the journal PLOS ONE. This is a fairly pedestrian paper about human hand anatomy and they conclude that anatomical structures provide evidence of a Creator. They conclude that since other primates show a slight difference in tendon connections, a Creator must be responsible for the human hand (well at least the slight, minor modification from earlier shared ancestors). Obviously this lazy science and an embarrassment to anyone that works as an honest scientist. But more importantly, it calls into question the Editor who handled this paper (Renzhi Han, Ohio State University Medical Center), but also PLOS ONE's publishing model. PLOS ONE handles thousands of papers and requires authors to pay for the costs of publishing. This may just be an aberration, a freak one-off, but the implications of this seismic f$@k up, should cause the Editors of PLOS to re-evaluate their publishing model.  

Things to keep in mind when finding a PhD

A wonderful student who worked with me when I was a graduate student is in the midst of applying for graduate school, and has been going through the process of finding a suitable program and advisor. It's been nearly 7 years (!?) since I was first in graduate school and, in my case, I mostly lucked my way from undergraduate to a great lab without nearly enough due diligence (and no one I knew or in my family had been to grad school to provide advice).

If asked during grad school, I had a list of advice I would have liked to have received (admin questions, funding issues, how to get to campus on public transport). But the advice I think is important has actually changed a lot, from just “make sure you love research” (although you should, at least most of the time), to more strategic and practical considerations.

I now think the most important thing is to ask yourself while you consider graduate school is, "Why do I want to get a PhD?" Note that there is absolutely no right answer to this question, but there are some wrongs ones, e.g. "I don’t know what else to do next" or "I have good grades". The problem is that these answers aren’t enough to motivate you through a PhD program. And some people find themselves 5 years later, still not knowing what they’re going to do next or why they got a PhD. It’s okay to answer "I like the research I did as an undergrad" or "I want to develop strong quantitative skills", or "I love working with ideas", because these kind of answers mean you want something from your experience and you've thought about what that is.

Educate yourself about the opportunities that a PhD will bring, both academic and non-academic. Continue this education while you are in graduate school. [Departments, offer more opportunities for students to learn about non-academic jobs.] The reality is that getting the oft-desired research professorship is very difficult (e.g. 200+ applicants for a general ecology position is not unusual). But PhDs produce desirable skill sets and there are other opportunities, so long as you are aware of them. There are many LACs (liberal arts schools) in the US, and thus more teaching oriented professorships advertised every year than there are R1 professorships. There are NGO and government research jobs. And as many of my grad school friends leave academia, it’s a relief to see that their skills – strong quantitative abilities, good data management, a clarity of vision on how to ask questions and answer them with appropriate data – make them employable across a range of professions.

Ask questions ask questions ask questions. Don’t go into a program without knowing what it will entail. Ask the same questions of both faculty and students and see how their answers compare. 

To understand a department, you want to know what the teaching load is on average, how funding works (and for how long!). You should find out the average time to completion of a PhD program, what classwork looks like, whether there are student-lead reading or discussion groups? Is there funding for student travel to conferences or meetings?

If you have a lab in mind, you need to similarly learn about that lab. Find out, from both the PI and their students, how the lab works. What is the supervisory style? Does the PI tend to be hands on, or expect more independent research? How does your personal approach to working mesh with their style? Don't assume that if you like to have structure and feedback and the PI only is around once a month, it will just work out. How often are they physically on campus? How often would you meet? What are other students in the lab working on? Is the lab collaborative? Do students publish together? What skills are emphasized in the group? Has the PI published recently (last 2-3 years, depending on context) and, perhaps most importantly, have they graduated any students? If not, try to figure out why.

Once you’ve found a place, remember that how you feel about your PhD will rise and fall all the time. That’s normal. Avoid the worst of these dips by taking care of your mental health. The sort of unstructured, isolating, often un-rewarded work that goes into a PhD can be draining. But it is also 100% okay to change your mind, to decide a Master’s is sufficient, to hate everything you are doing and quit. Seriously. The sunk-cost fallacy will make you (and people around you) miserable.

Of course, grad school—like life—is stochastic and full of uncertainty. But its possible, with care to increase the probability that you find a supportive, nurturing lab and have a wonderful time as a graduate student. 

Resolutions for 2016

Having now been a postdoc for a couple of years, I think I’ve slowly developed more perspective about the day-to-day aspects of working as a researcher and the costs and benefits of various approaches. So this year, I am resolving to be proactive about the various challenges of academic life, and try some things meant to make my work life more productive and better: 

1) Carve out more time to read the literature. The busier I get, the more difficult it is to keep up with new papers that aren’t directly connected to my current projects. One of the best parts of being a grad student (without a heavy teaching load) was how much time I had to keep up with the literature. As my time is more scheduled and there are more concrete deadlines, it is harder to make time for activities like reading that don’t have an immediate pay off. I have a feed reader, but I find that I only check it monthly; I also come across interesting papers while doing lit reviews/etc and leave those open in my browser, planning to get to them eventually...

I know that braver souls than I are tackling this problem #365papers style, but I don’t think that’s what I want. Instead, I am scheduling three 1-hour slots per week, and I think that’s a manageable goal.

2) Continue to work on good project management practices (such as those described here). I use the suggestions for predictable directory structures, separation of code into different types of scripts and of course, version control, and find them very helpful. I wish that I had learnt best practices for coding and project management as a grad student, but it’s never too late.

3) Take vacations (and mean it!). Every academic I know who has good work-life balance takes vacations. That means not working—at all, including no responding to emails. This is one of the things I admire most about my European colleagues, and I look forward to enjoying the French holidays when I start a fellowship in Montpellier this spring :-)

4) Maintain relationships across distances. It can be difficult to connect with people during short postings here and there, and even harder to maintain those relationships after you move on to the next place. The tools are there (Skype, Facebook, Twitter, email, etc), so I shouldn’t forget to take advantage of them.

5) Learn a new skill. Still deciding what, given the many things I want to learn!

6) Emphasize the positive more often. In general, I think people (or at least me) can be overwhelmed by the negatives in academia – e.g. the rejections of manuscripts and applications, the difficulties in securing the next job, etc. Unlike in undergrad, we don’t get grades or quantitative measures of our success too often (and I haven’t gotten a sticker on my work in years). And when we do get praise, it is often informal (e.g. “good talk”, “I liked your paper”), or balanced with criticism (e.g. “accept but with major revisions”). This is all in pursuit of improvement, but it can be difficult to keep even constructive criticism in perspective because the brain is biased towards remembering the negative. So I’m considering keeping an explicit list of successes to help highlight the positive.

The hurdles and hardships of science in China

In my last post on China I discussed why China is becoming a scientific juggernaut. I focussed on all the things that seem to be working in its favour (funding, high expectations on scientists, etc.). While I do think that science in China is good and getting better, it is also important to point out some of the hurdles and limitations that hold back some aspects of scientific advance here.

In my previous post I noted that the expectations placed on students and researchers (i.e., to produce a minimum number of papers in journals with high impact factors, IFs) provided motivation to do good science. This is undoubtedly true, however, these strict expectations also reinforce a strategy of ‘paper-chasing’ where students are encourage to figure out how to get a paper. This is because the reward structure is so quantitative. While this type of evaluation systems has pros and cons, it does create a different sense of urgency than I’ve experienced elsewhere.

Pragmatic factors

The Great Fire Wall of China from "Cracks appear in the Great Fire Wall of China" posted by the China Daily Mail, Sep. 25th 2013.

I have never yelled at my computer or cursed the internet as much as I have in China. In the west we often hear about the ‘Great Firewall of China’ and probably do not think much about what this actually means. It sucks. The internet barely functions for significant proportions of the working day. I thought that this might have to do with the number of people and lack of infrastructure, but I no longer believe this to be true. Other countries in the region have great internet, and China has very advanced infrastructure. I’m pretty sure that when there is high traffic, the national security protocols and activity monitoring servers are the bottleneck.

Because the government policy is to block certain websites, most of the scientific internet websites and data sharing portals are not accessible here, but this may change at any given time. For example: Google Drive, Dropbox, Facebook, Blog sites, Twitter, Google Maps, and Google Scholar are all services routinely used by scientists and which are blocked in China. The reason for these to be blocked, as far as I understand it, is that they do not share users’ activities and the government cannot monitor what individuals share and download (which reinforces the value of these services to me). I also suspect that they are blocked to give local companies a chance to succeed without competition from global corporations, or perhaps simply because of disagreements with the companies.

I have had immense trouble trying to share files with my lab back in Canada (and to post this blog entry –which is why I’m doing it from Cambodia!). I am not currently engaging in social media –something that I saw as a legitimate activity for communicating science. I am having a very hard time searching for articles without Google Scholar. I also have trouble with other websites that should not be blocked, but that use third party encryption. For example, I can’t log in to my University library in Toronto, and I couldn’t connect my Canadian grant application to the Canadian Common CV (which we are required to do in Canada) because the CCV web interface was blocked (I had to get my post doc in Canada to do it for me). I have tried to go to researchers’ websites to find that they are blocked because they use a blogging site (e.g., Wordpress). The amount of time I spend doing basic online professional activities has increased 3 to 4-fold.

This is important because Chinese scientists are at a disadvantage when it comes to international collaboration and participating in online initiatives. I would encourage scientists outside of China to consider these imposed limitations to ensure that information and collaboration is barrier-free. Here are some tips:

1. Don’t link to your Google scholar publications on the publications page of your website
2. Don’t use a blog site to host your website (e.g., Wordpress)
3. Don’t use Dropbox or Google drive to collaborate on papers
4. Don’t use gmail as your work e-mail, Air China, for example, won’t send e-mails to gmail.
5. Social media has emerged as a great way to communicate with broader communities, it is important to recognize that these dialogues exclude Chinese scientists.
6. Ironically, as I write in this blog, blogs are blocked and while blogs provide a great platform to discuss ideas and issues, they are not available to Chinese scientists. 

These last two are interesting as journals increasingly require or request tweets or blog posts to help maximize exposure, but these forms of communication are not on scientists’ radar here.

Chinese science has been increasing by leaps and bounds despite these limitations. This is a testament to the hard work and dedication by Chinese scientists. I have no doubts that basic scientific research in China will continue to increase its stature and impact.

Postscript

One thing that is interesting to me is that many of the graduate students here use VPNs (Virtual Private Networks) to mask their IP addresses. They are able to access blogs, Google Scholar, etc. In conversations with people, VPN use is extremely widespread and successful at circumventing government filters, most of the time (there seems to be an arms race between the government and VPNs). It really makes me wonder how much longer these governmental controls can be realistically maintained.

Science in China –feeding the juggernaut*

For those of us involved in scientific research, especially those that edit journals, review manuscripts or read published papers, it is obvious that there has been a fundamental transformation in the scientific output coming from China. Both the number and quality of papers have drastically increased over the past 5-10 years. China is poised to become a global leader in not only scientific output, but also in the ideas, hypotheses and theories that shape modern scientific investigation.

I have been living in China for a couple of months now (and will be here for 7 months more), working in a laboratory at Sun Yat-sen University in Guangzhou, and I have been trying to identify the reasons for this shift in scientific culture in China. Moreover, I see evidence that China will soon be a science juggernaut (or already is), and there are clear reasons why this is. Here are some reasons why I believe that China has become a science leader, and there are lessons for other national systems.

The reasons for China’s science success:

1.      University culture.

China is a country with a long history of scholarly endeavours. We can look to the philosophical traditions of Confucius 2500 years ago as a prime example of the respect and admiration of scholarly traditions. Though modern universities are younger in China than elsewhere (the oldest being about 130 years old), China has invested heavily in building Universities throughout the country. In the mid-1990s, the government built 100 new universities in China, and now graduates more than 6 million students every year from undergraduate programs.

Confucius (551-479 BC), the grand-pappy of all Chinese scholars

This rapid increase in the number of universities means that many are very modern with state-of-the-art facilities. This availability of infrastructure has fostered the growth of new colleges, institutes and departments, meaning that new faculty and staff have been hired. Many departments that I have visited have large numbers of younger Assistant and Associate Professors, many having been trained elsewhere, that approach scientific problems with energy and new ideas.

My new digs

2.      Funding

From my conversations with various scientists, labs are typically very well funded. With the expansion of the number of universities seems to have been an expansion in funds available for research projects. Professors need to write a fair number of grant proposals to have all of their projects funded, but it seems that success rates are relatively high, and with larger grants available to more senior researchers. This is in stark contrast to other countries, where funding is inadequate. In the USA, National Science Foundation funding rates are often below 10% (only 1 in 10 proposals are funded). This abysmal funding rate means that good, well-trained researchers are either not able to realize their ideas or spend too much of their time applying for funding. In China, new researchers are given opportunities to succeed.

3.      Collaboration

Chinese researchers are very collaborative. There are several national level ecological research networks (e.g., dynamic forest plots) that involve researchers from many institutions, as well as international collaborative projects (e.g., BEF China). In my visits to different universities, Chinese researchers are very eager to discuss shared research interests and explore the potential for collaboration. Further, there are a number of funding schemes to get students, postdocs and junior Professors out of China and into foreign labs, which promotes international collaboration. Collaborations provide the creative capital for new ideas, and allow for larger, more expansive research projects.

4.      Environmental problems

It is safe to say that the environment in China has been greatly impacted by economic growth and development over the past 30 years. This degradation of the environment has made ecological science extremely relevant to the management of natural resources and dealing with contaminated soil, air and water. Ecological research appears to have a relatively high profile in China and is well supported by government funding and agencies.

5.      Laboratory culture

In my lab in Canada, I give my students a great deal of freedom to pursue their own ideas and allow them much latitude in how they do it. Some students say that they work best at night, others in spurts, and some just like to have four-day weekends every week. While Chinese students seem equally able to pursue their own ideas and interests, students tend to have more strict requirements about how they do their work. Students are often expected to be in the lab from 9-5 (at least) and often six days a week. This expectation is not seen as demanding or unreasonable (as it probably would be in the US or Canada), but rather in line with general expectations for success (see next point).

Labs are larger in China. The lab I work in has about 25 Masters students and a further 6 PhD students, plus postdocs and technicians. Further, labs typically have a head professor and several Assistant or Associate Professors. When everyone is there everyday, there is definitely a vibe and culture that emerges that is not possible if everyone is off doing their own thing.

The lab I'm working in -"the intellectual factory"

Another major difference is that there is a clear hierarchy of respect. Masters students are expected to respect and listen to PhD students, PhD students respect postdocs and so on up to the head professor. This respect is fundamental to interactions among people. As it has been described to me, the Professor is not like your friend, but more like a father that you should listen to.

What’s clear is that lab culture and expectations are built around the success of the individual people and the overall lab. And success is very important –see next point.

6.      Researcher/student expectations

I left the expectations on researchers for last because this needs a longer and more nuanced discussion. My own view of strict expectations has changed since coming to China, and I can now see the motivating effect these can have.

For Chinese researchers it is safe to say that publications are gold. Publishing papers, and especially the type of journal those papers appear determine career success in a direct way. A masters student is required to publish one paper, which could be in a local Chinese journal. A PhD student is required to publish two papers in international journals. PhD students who receive a 2-year fellowship to travel to foreign labs are required to publish a paper from that work as well. For researchers to get a professor position, they must have a certain number of publications in high-impact international journals (e.g., Impact Factor above 5).

Professors are not immune from these types of expectations. Junior professors are not tenured, nor are they able to get tenure until they qualify for the next tier, and they need to constantly publish. To get a permanent position as a full professor or group leader, they need to have a certain number of high impact papers. For funding applications, their publication records are quantified (number and impact factors of journals) and they must surpass some threshold.

Of course in any country, your publication record is the most important component for your success as a researcher, but in China the expectations are clearly stated.

While there are pros and cons of such a reward based system, and certainly the pressure can be overwhelming, I’ve witnessed the results of this system. Students are extremely motivated and have a clear idea what it means to be successful. To get two publications in a four year PhD requires a lot of focus and hard work; there is no time for drifting or procrastinating.

So why has Chinese science been so successful? It is because a number of factors have coalesced around and support a general high demand for success. Regardless of the number of institutional and funding resources available, this success is only truly realized because of researchers' desire to exceed strict expectations. And they are doing so wonderfully.  

*over the next several months I will write a series of posts on science and the environment in China
