Extrasolar Planets—I am interested in searching for and characterizing directly imaged exoplanets from the ground and space. I am Co-PI of the JWST Early Release Science program for imaging exoplanets.

Cold Brown Dwarfs—I obtained the first spectrum of the coldest known brown dwarf, WISE 0855, which at ~250 K, is the first object outside of our Solar System to show evidence for water clouds.

Instrumentation—I work on instruments that are optimized for focused studies of exoplanets, including LBTI, ALES, SCALES, PSI, PEAS and KPIC.
