I specialize in working with time-series ultraviolet data to characterize exoplanetary systems. My initial work as a grad student quantified for ~40 stars the short-timescale variability of the stellar UV emission lines used to probe evaporating exoplanetary atmospheres. Following this, I turned up null results searching for light-reverberations in T Tauri disks and evidence of star planet interactions in the GALEX time series data. Currently, I am assembling a library of spectral energy distributions of 11 low-mass planet hosts and studying the flaring behavior of these stars to assess the effect of flares on atmospheric evolution as my thesis work.
