I picked up rowing during graduate school, as the Charles river might be the best place to learn rowing outside of Britain. I was fortunate to row in the Dudley House men's eight for several years, and I entered the World Indoor Rowing Championships twice (and didn't even come close to winning).
I've been a mid-distance runner since middle school. I don't run particularly far or fast, but it's a great way to clear my head. Sometimes you can find me at local races.
I picked up the game as a senior in high school and played a little club in college. Although I don't play as often as I'd like, I always keep two discs in the trunk of my car. Now you know who to ask.
I'm a fan of open source software. I suppose it's related to my belief in reproducibility in science. Some of my projects are hosted here.
I occasionally moonlight as a community resource for games I play. I decided to make a permanent place to collect posts and tools.
I used to write about problems that I found engaging in a blog. I haven't written in a while, but it was fun, and I'm not ruling out starting up again.
