Sagan Fellow, CfA/SAO

I am a postdoctoral researcher at the Harvard-Smithsonian Center for Astrophysics. I am interested in the high-energy environment of exoplanets, how X-rays and UV photons impact the planetary atmosphere, and how close-in planets can influence their host star's magnetic properties. In my research, I use high-energy data from space telescopes as well as high-resolution optical spectra from ground-based observatories to learn more about exoplanetary systems.
