My research focuses on stellar activity and its effect on exoplanets. I use the Hubble Space Telescope to observe the UV spectra of nearby exoplanet host stars, primarily M dwarfs. UV observations reveal information about magnetic activity on stars as well as measure the high-energy radiation observation of orbiting exoplanets. UV light and its variability in time strongly affects exoplanet atmospheres through heating and mass loss, photochemistry, and likely prebiotic chemistry on the surface.
