A Day in the Life of …

Today was a great day – busy and wonderful. Pretty typical, I’m happy to say, though a bit busier than usual but all of it great.

Woke up to beautiful Spring day in East Lansing and walked 1.7 miles to work at MSU.

Did the usual email stuff.

Worked on getting ready for teaching for a class on evolutionary medicine taught by my colleague Jim Smith. Today’s focus will be the paper by Tami Lieberman et al. on the evolution of Burkholderia dolosa in cystic fibrosis patients during an outbreak in Boston. Last night I re-read the paper for the umpteenth time, and I still enjoyed it. Today I organized a series of questions for the students – a very interactive and smart group – around three parts.

Part I: Some background about CF, the inheritance of this disease, the frequency of the disease, how that frequency allows one to estimate the frequency of carriers, why the allele might be so common (not understood), side questions about sickle-cell anemia and why it’s so prevalent, and why, if it’s inherited, the paper we read is all about infections.

Part II: Preparing slides so we could work our way, figure by figure and panel by panel, through all of the main points in Lieberman et al.  (Reminder: Explain to students how scientific papers are often written around figures.  Once the figures and tables are there, then start on the results, etc.)

Part III: Follow up questions about the paper, the system, the interface of epidemiology and evolutionary biology, prospects for the future of this field and the students’ careers (most in this class are premed, many with a research bent), etc. And whatever questions they might want to ask of me.

Sometime in the middle of doing all that: Chatted with second-year grad student Jay Bundy, who is reading some of Mike Travisano’s terrific earlier papers on the LTEE. Specifically, why do we sometimes express fitness as a ratio of growth rates (measured in head-to-head competitions) and sometimes as a difference in growth rates?

Also in the middle of doing all that: Had phone conversation with former Ph.D. student Bob Woods, now also an M.D. specializing in infectious disease, about a faculty job offer he has (congrats, Bob!), some of the issues he needs to clarify or negotiate, and some of the amazing work he’s now doing on the population dynamics and evolution of nasty infections.

Email from grad student Mike Wiser that our paper, submitted to PLOS ONE, has been officially accepted. We had posted a pre-submission version at bioRxiv – now it’s gone through peer-review and revisions and is accepted for publication. Congrats, Mike!

Got a draft of the fourth and final chapter of Caroline Turner’s dissertation. The first three chapters are in great shape. Congrats, Caroline! With teaching looming, I had only time to review the figures, tables, and legends on this one, and made some small suggestions. On to the text tomorrow … It’s a beautiful body of work on two fascinating aspects of the interplay between ecology and evolution that have emerged in the LTEE and another evolution experiment that Caroline performed. Stay tuned for these papers!

Took a phone call from an MSU colleague who has friend with a child in high school who is interested in microbiology, who is visiting MSU, and who wanted to see the lab. Yikes, I gotta run teach! But postdoc Zack Blount kindly agreed to give a guided tour as I headed off to teach.  Thanks, Zack!

Beautiful day continues as I walk to teach in another building. Touch base with Jim Smith about what I plan to cover.

Two straight hours of teaching (one 5-minute break) in an overly hot room. Almost all of it interactive, with me asking questions and the students conferring in small groups and then responding. Very interactive, very bright students! The two hours were nearly up, with little time for my third, post-paper set of questions. But all of the students stayed (despite the beautiful weather, hot room, and the dinner hour at hand) an extra 15-20 minutes for a couple of my questions and some great ones from them about the LTEE and the future prospects for microbial evolution in relation to medicine.

It’s 6:20 pm: I’m mentally exhausted but equally invigorated. Beautiful Spring day continues as I walk home. I’m greeted by our lovely hound, Cleopatra. Exercise and feed her. Then an even more lovely creature, Madeleine, returns home and I greet her.

Check email before dinner. Find that paper with grad student Rohan Maddamsetti and former postdoc Jeff Barrick has been provisionally accepted, pending minor revisions, at Genetics. We posted a pre-submission version of that paper, too, at bioRxiv. Though we still need to do some revisions, I think it’s fair to offer congrats to Rohan and Jeff, too!

Time to crack open a bottle of wine and have some dinner. Fortunately, some of the pre-packaged dinners are pretty tasty and healthy, too, these days ;>)

Refill wine glass. Sit down and start to write a blog on a day in the life of …

  2. Rich, this surely can’t be any average day. Congratulations to you and all of the gang on all of these wonderful successes. As I’ve always said, if you build a great team, everyone makes each other better.
