I’m a graduate student at the Caltech Department of Astronomy.  I’m interested in the radio emission from stellar flares and atmospheres, although I’ve had other adventures in radio astronomy involving dust and supermassive black holes.

Follow the links at the top of the page to check out my research, teaching and outreach, and some photos and notes from my visits to radio telescopes around the world.
