time management tips for assistant professors (and everyone)

I recently saw a short list of advice for new assistant professors by Chris Blattman [Link]. Chris is an Assistant Professor of Political Science & International and Public Affairs at Columbia University (soon to be tenured). His list is summarized below. Go to his blog post for the full discussion:

  1. Learn to say no to new projects.
  2. Have a higher bar for projects with big exit costs.
  3. Book chapters and reviews are a waste of time.
  4. Get your dissertation papers or book out.
  5. Seek out mentorship.

This list is not comprehensive. This is not a weakness, but rather an opportunity to add to the list. The above list solely focuses on research and publication for assistant professors at research intensive universities.

I have a few things to add to the list. My tips, however, narrowly focus on time management. Most aren’t just for academics.

I was on a panel at the 2012 INFORMS Annual Meeting about time management for assistant professors hosted by the Junior Faculty Interest Group. Other panelists included Mark Lewis (Cornell), Kathy Stecke (UT-Dallas), and Brian Denton (now at Michigan). The panel discussion was chaired by Shengfan Zhang at the University of Arkansas. I had recently been awarded tenure from my previous university, and Shengfan asked me to talk about how I managed to get tenure with three kids. I only had a few minutes, so I focused on four general principals of time management that I use:

  1. There are two basic rules for time management: Do less or do it faster. There are no real tricks. I recommend learning how to say no to superfluous department, college and university service that will not add value to a tenure case and to be careful with collaborations.
  2. 80% of success is just showing up.  Academics of both genders with kids married to working non-academics tend to be the “flexible” ones, who attend to children’s doctors appointments, sick days, and days off of school. It can add up unless a fair plan is in place.
  3. Be careful with how you work on the weekends and evening. This seemingly contradicts #2, but it really takes a different angle. It’s important to work “enough” but to also put in quality time. Parkinson’s Law: Work expands to fill the time available for completion, so set deadlines and give tasks less time.
  4. Make time for the important but not urgent things. I do this by getting things done before deadlines, staying on top of email (I’m learning this is much harder to do as a tenured professor), getting sleep so that I can focus on important tasks and every day. Yes, sleep is important. If I didn’t follow this advice, I would be constantly putting out fires for looming deadlines rather than working toward my research portfolio. You won’t magically have more time in the future—now is a great time to cross something off your to do list.  This idea is consistent with Stephen Covey’s “Big Rocks First” management strategy
    • Corollary: Never be so busy that you are not a good colleague—it matters for tenure (and for life).

If you want a comprehensive list, the best I have seen is Shane Henderson’s paper “Staying Sane ont he Tenure Track” published in the 2008 Winter Simulation Conference [Link]. My favorite part:

Do not work 14 hours a day, assuming life gets calmer after tenure. It doesn’t. It gets busier

Bill Cook’s TSP talk at the University of Wisconsin-Madison

On Monday, Professor Bill Cook, Professor in Combinatorics and Optimization at the University of Waterloo gave the Hilldale Lecture at the University of Wisconsin. See my earlier blog post about this here.

Bill’s talk on the Traveling Salesman Problem (“One NP-hard problem to rule them all“) was terrific! Bill is a master multi-tasker as evidence by how he effortlessly controlled his talk on three separate screens by three iPhones that he carried around his talk (one was strapped to his wrist).

Bill gave a great overview talk about the TSP. He talked about the history of the TSP and the main contributions, the intuition problem behind proving tours are optimal using linear programming duality and why cutting planes are helpful, and why heuristics work so well, and challenges for parallelizing the algorithms. I highly encourage reading Bill Cook’s book In Pursuit of the Traveling Salesman to learn more.

Fun TSP fact: One of the early mentions of the TSP was made by a report by Julia Robinson of the RAND Corporation in 1949, who published On the Hamiltonian game (a traveling salesman problem) [Link].

Another fun TSP fact: More recently, a woman started a 50 first dates quest via Kickstarter, where she would have a date in each of the lower 48 states plus DC and Canada [Link]. She will tour the cities and make a documentary about it. (Side note: She will probably talk about her dates more than about math in the documentary – I bet she won’t even mention cutting planes once!)

In 2012 Bill ran a TSP challenge that boasted a winning prize of $500 for finding the best tour in a 115,475-city challenge through (nearly) all cities, towns, and villages in the contiguous 48 states. [Link]. The three best tours all independently found different tours of the same length. A good approach for finding a near-optimal tour in a big TSP instance is to use a combination of local search and genetic algorithms. Local search tweaks part of a tour to make it slightly better. Genetic algorithms mix different tours to take good partial tours from two potential solutions to (potentially) find a better tour that combines their best parts. The combination is powerful. Bill has a few new TSP challenges and it sounds like he’ll buy you a beer if you solve them. Another fun fact: If you want a bigger prize, The Clay Institute offers a $1 million prize for finding a polynomial time algorithm for solving TSP.

Bill mentioned that fast computers helped to solve hard TSP instances but not for the reason that you might think. The fast computers and processors we have now are more accessible than the supercomputers that were used in early TSP research. Now we can tinker with computer algorithms on a laptop (or phone), and this helps to reduce the feedback loop in research, and the faster feedback is helpful for driving good research (more so than the fast computing itself).  I am young enough that I was surprised by one  of Bill’s comments about a 1987 TSP algorithm that took 23 hours on a supercomputer, “We were all surprised they were allowed to use that much computing time.” Time has certainly changed.

Bill ended the talk by hinting at future research directions including time travel and parallelization. Recently, there have been some publications that suggest that monkeys [Link] and bees [Link] solve TSP instances. But Bill was skeptical that monkeys will assist us with the next TSP algorithm breakthrough.

my talk at the University of Michigan IOE department

On Friday I gave a seminar at the University of Michigan’s Industrial and Operations Engineering Department. I was invited by the INFORMS student chapter and the Michigan IOE Diversity Initiative headed by Mariel Lavieri. I owe a special thank you to the INFORMS Speakers Program that subsidized the cost of my trip.

Women, minority, and international students attended the lunch. I was overjoyed to speak to such a large, diverse group including some students not from under-represented groups (white men). As I’ve written about before, you don’t need to be from an underrepresented group to want everyone to feel welcome at the table. Some of the best advocates of researchers from underrepresented groups that I know happen to be white men. I was delighted that all attended and asked great questions and shared a variety of experiences.

Questions ranged from raising three children to biases to biases that I’ve internalized to INFORMS WORMS initiatives. I tried to maintain a good balance of positive things with things that could use some improvement. The students were surprised to hear that I only had one women engineering professor in college and had been the only women in some of courses I took in graduate school. I’m glad that some of these things have changed! I especially liked hearing the students talk about their experiences and impressions.

I was impressed with how many students attended and participated in the program. Kudos to Mariel Lavieri, who has done a fantastic job with the diversity initiative and encouraging students to attend my talk. After the seminar, the students and faculty gathered in a lounge to enjoy snacks and each other’s company.

  6. There is so much to say about this figure. Men are unphased by Bs in introductory courses, but it causes women to switch majors! There is much to say about this. I’ll just say that there are some real challenges to retain women in STEM disciplines unless we give out all As in introductory courses (which I do not advocate).

  2. Evelyn Lamb at Scientific American blogs about the math behind a perfect bracket.
  3. Carl Bialik at FiveThirtyEight writes about the odds of getting a perfect bracket using analytical methods. It depends on how good those analytical methods are. Nate Silver claims it might be as high as 1 in 7.4 billion. Interesting.
  4. Will a 16 seed ever beat a 1 seed?” by Ed Feng (@thepowerrank) Ed also has a bracket tool that visualizes different game outcomes.
  5. My advisor Sheldon Jacobson who maintains BracketOdds was interviewed in the News-Gazette, the local paper in Champaign-Urbana, IL.
  6. The Huffington Post has a “Predict-O-Tron” that helps you fill out your bracket using a probabilistic tool that lets you set the importance of different attributes (like seed, offensive efficiency, and even tuition) using moving sliders. It looks interesting but reeks of overfitting.
  7. I was on the local NBC 15 affiliate in Madison on March 18 to discuss the odds of a perfect bracket (video included).

Good luck perfecting your bracket!
