Cosmic rays from Voyager 2

New results from an old spacecraft, revealing fascinating complexities at the boundary between the heliosphere and interstellar space. This is work from my PhD advisor and colleagues. These boundaries between our local space environment and the larger Galaxy have always interested me.

Presolar Grain Workshop

We’ve just returned from the Presolar Grain Workshop, held at U. Chicago this year. It was a fantastic weekend — I learned a lot, developed some exciting new ideas for research projects, and made new friends. A highlight was our dinner *inside* the Field Museum, a tour of the U Chicago CHILI lab, and seeing some great meteorites up close (including a ~200 kg pallasite and a beautiful lunar meteorite).
