Welcome to my blog! I am an American astrophysicist living in Bordeaux (France) with my wife Marisa and our two sons. I study the formation and evolution of planetary systems. In my research and on this blog I ask questions like:
- Where did Earth’s water come from?
- Which extra-solar planetary systems are the best for life? and
- Why does our Solar System appear to be different than planetary systems around other stars?
In this blog I try to balance imagination with science. Sometimes I “play God” and design other planetary systems (for example, here and here). Sometimes I evaluate the setting of science fiction stories (see here). These designs are constrained by what kinds of systems could actually form and remain stable. I also sometimes break out Dr Seuss-style astronomy poems (see here).
You are welcome to check out my research website, where you can find a summary of my research and a list of my publications. Here is a talk I gave at Google a few years ago. Here and here are talks I’ve given recently on planet formation (to somewhat technical audiences). I also enjoy giving talks to the general public (see for example, here and here).
In my spare time I enjoy hanging out with my wife Marisa and two sons. I also play ultimate frisbee, hike, and do other silly things.
