I am a Senior Astrophysicist at the Smithsonian Astrophysical Observatory of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, USA. I study the high energy aspects of stellar physics and how they impact star and planet formation, stellar evolution, and planetary radiation environments.
