I am always eagerly searching for talented and self-motivated students and researchers to join my research group. The greatest aspect of my job is undoubtedly the privilege to work with dedicated students and colleagues who are motivated to do original work. Nevertheless, going to graduate school or working as a postdoc is a very substantial commitment for all parties involved. Since joining Columbia in 2014, I have graduated four Ph.D. students, two of them found tenure track positions (McMaster and Northeastern), and two joined Los Alamos National Laboratory as postdoc research associates. Two of my former postdocs are now assistant and associate professors at the University of Hong Kong and the Chinese Academy of Sciences (see specific job placements in team member page [URL]). That being said, the success of a PhD student depends on many different factors and compatibility is an important one to consider. If you are interested to join my research group, you might find the information below somewhat helpful.
General Recruitment Plan
Generally speaking, I try to recruit one to two graduate students or postdoc per year, depending on the availability and time constraint of funding and my ability to maintain the quality of the research with the existing students and postdoc research associates. My goal in the hiring process is to filter the candidates that are less likely to be successful under my tutelage while trying not to miss any talent that may have potential to do great research.
The PhD application process begins in the Fall semester each year. The review of the Ph.D. applications typically begins in the spring and ends before the summer. Ideally, the successful Ph.D. candidates should have (1) a master degree in civil engineering, applied mechanics, geomechanics, applied mathematics, or other related disciplines, (2) some background in computational mechanics and reasonable mathematical skills (e.g. linear algebra, partial differential equations), (3) be proficient in Python, C++, Java and/or FORTRAN code developments, and (4) possess excellent communication skills. At the beginning of the Ph.D. study, I expect that the incoming students are at least competent in basic linear algebra and calculus, and have some general ideas about mechanics. In the past, the maximum team members I recruited in one single year is 3, the lowest is 1. My philosophy is that a student may graduate whenever she/he has a great chance of landing a great position, according to the best of my judgment. Ph.D. students in my group on average takes four years to finish their Ph.D. studies if they have a master's degree in a related field. All of my current and former PhD students in my research group have been fully funded while they work with me. They are supported by a combination of fellowships (Fulbright, NDSEG, Presidential fellowship), research assistantship from research grant and teaching assistant support. If the resource is available and that is understandably not always the case, my goal is to have each student serves at least once as TA to get some teaching experience (especially if they are interested at academic position) within the first 2 years of PhD study and then support the last two years of all of my PhD students' work with RA or fellowship. Postdoctoral applications are reviewed continuously. In some cases, it is possible that I would also hire or promote an associate research scientist for a specific research task. Postdoc candidates are recruited based on (1) research accomplishment, (2) future potential, (3) joint interest in the funded research topics, and (4) compatibility, and (5) the research group they graduate from and if applicable (6) the performance of my previous postdoc graduated from the same group of the candidates.
I encourage the applicants who are seriously considering working with me to talk to my current team members as well as the former ones to get a fuller and more balanced picture of the level of commitment required to be successful in my group and the work-life balance. I also encourage students from the underrepresented groups to join us.
Advising and research styles
While working with Ph.D. students and postdoc fellows, my goal is to find a research theme that (i) makes the student and I both excited about the work, (ii) matches well with the student's key competencies, personality, and work habits, (iii) contains elements that are of fundamental importance, (iv) has sufficient chances to find sustainable funding during and, ideally, beyond the Ph.D. study. As your research advisor, it is my duty to (1) provide an intellectually stimulating and safe environment for group members to conduct meaningful research, (2) to motivate you to set a high standard for your own research, (3) to provide the nuclei of research ideas, (4) to help you pursue research ideas as efficiently as possible, and (5) to evaluate your intellectual growth critically. In essence, my goal is to help you do the best research possible and keep you funded, focused and motivated.
Expectations on students and postdoc associates
It is a requirement that all Ph.D. students and postdoc research scientists must be able to produce research results worthy of publishing in well-respected peer-reviewed journals within a reasonable amount of time in my research group (e.g. Computer Methods in Applied Mechanics and Engineering [PDF1][PDF2][PDF3][URL], Journal of Engineering Mechanics [PDF], International Journal for Numerical Methods in Engineering [PDF] and International Journal of Analytical and Numerical Methods in Geomechanics [PDF]). All postdoctoral scholars and graduate students remained as our team members beyond the first year have continued this trend with no exception.
It is expected that all team members in this research group, including myself, would set the highest standard on their work and thrive to conduct high-quality research that impacts our research field. Good habits which I found in many of my current and former students and postdocs, include showing up in group meeting prepared and on time, making sure that all results presented in the papers are easily reproduced if needed, keeping a written record of the research progress, paying attention to the details of a research idea, and being honest when analyzing the data and interpreting the experimental results. Please note that we have a zero-tolerance policy on falsification, fabrication and plagiarism as well as other misconduct [URL].
Time management
I do sincerely hope that all team members will value their own time as well as mine. While many activities can be beneficial, knowing how to set priorities and stay focus is one of the most important skills you will learn in graduate school. Provided that the time investment is justifiable, you may found yourself formulates research direction, brainstorm ideas, check derivations, proofread manuscripts, discuss problems, provide feedback, rehearsal presentations, prepare job interviews, and handle the paperwork daily often within a very limited amount of time. While I will involve in those activities with you and share some of the workloads, there will be moments at which you feel overwhelmed.
I have two suggestions for all the team member. First of all, please do to not give priority to all activities that sound important. Use your judgment and common sense to invest time in things that truly matter to you and your research. A distinctive characteristic of our profession is that the work requires a lot of creativity and mental concentration. It is important to have enough mental space and avoid saturating your daily life with numerous distractions. Bad examples of time management include attending a lot of zoom meetings without sound reasons and spending too much time on activities that dilutes the focus. Multi-tasking all the time. Don't surround yourself with noise, music, phone call all the time. Cherish the moment when you are mentally sharp. Use your less optimal time to deal with routine works that do not require a high level of concentration (e.g. filling out reimbursement forms, handling paperwork..etc). My second suggestion is to just pick at most three items that you try to achieve every day and forget the rest of them until the prioritized items are completed. There are tools, such as Google Tasks that are synchronized with a calendar. Be realistic about your ability and learn how to say no could be critical to your success. Turning off all the notifications in your browser and cell phone also helps.
It is a good idea to think about the time in different scales. Your time in graduate school is very short but it is also the defining moment of your career. Your action today may affect your career trajectory for next few decades. Reinforce the good habits and try to learn from the mistakes and things will eventually work out one way or the other.
Dealing with stress, failures, and setback
In many cases, your success is often dictated far more by your motivation, attitude, patience, integrity, and discipline than your talent. High expectations unavoidably lead to disappointment from time to time. Learning how to handle unexpected failures is an important skill we acquired in life and in academia. If there is any unexpected bad news or setbacks, it is your duty to notify me immediately and it is my duty to identify the issues as soon as possible and work out a feasible solution with you. Don't be afraid to make mistakes and be patient and keep an open mind when things do not go your own way. Furthermore, you should care about the quality of your work deeply and keep an open mind to critiques, but it is not helpful to tie up your self-worth on someone else's evaluation of your work (Sternberg, 2015).
It is also important to build a supportive network of friends and colleagues that can enrich your life. Going to lunch and dinner with your fellow students and engaging in a health dose of social activities are not just helpful for networking but are beneficial for mental health. Some reality check and advice on life as a graduate student and an early-career researcher from different viewpoints can be found in Gassman (1988), PCM (2008), Hardevella et al. (2015), Terence Tao, recently Baker (2020).
