I'm an Einstein Postdoctoral Fellow at Caltech.
My research focuses on revealing the particle nature of
dark matter using observational
probes such as gamma rays and other high-energy particles.
I'm an Affiliated Scientist
in the Fermi Gamma-ray Space Telescope collaboration, and a member of the Cherenkov Telescope Array (CTA) Consortium.
I also organize a dark matter group at Caltech.
