Research My research relates to the detection and characterization of long-period Interests exoplanets, both in transit and radial velocity observations. I aim to understand how observations of these exoplanets inform planetary for- mation and evolution theories. I also model refraction in exoplanetary atmospheres using custom radiative transfer codes.
