Hello! I'm a Ph.D. candidate in the Geophysics program at MIT, working with Dan Rothman. I use simple math to describe natural systems. Previously, I worked with Tanja Bosak, studying microbial controls on the Earth's carbon cycle. Prior to my arrival at MIT, I received a Bachelor's degree in Physics from Harvard University, where I studied acoustic anomalies with Eric Heller and soft condensed matter with Adam Abate and Dave Weitz.

I am fascinated by stream networks. Their incision in landscapes can create highly ramified networks, whose dynamics can [sometimes] be described by surprisingly simple mathematics.

*They're also pretty.*

But I'm interested in any pretty math and complex natural systems in general, so if you find something you think I'd find interesting, let me know!

I once considered myself a classically trained violinist and pianist, but have since moved on to songwriting.
