My work focuses on 1) observations of planet-forming disks around nearby young stars and 2) development of future missions to observe planets around other stars, aka. exoplanets.

Selected Projects

From 2016 to 2019, I was the Study Scientist for the LUVOIR Decadal Survey Mission Concept Study. The Large UV / Optical / IR Surveyor (LUVOIR) is envisaged a highly capable, multi-wavelength observatory with ambitious science goals.

One of LUVOIR's primary aims is detailed investigation of a wide range of exoplanets, including those that might be habitable - or even inhabited. LUVOIR would also enable great leaps forward in a broad range of space science, from the early universe, through galaxy formation and evolution, star and planet formation, to remote sensing of Solar System bodies.

From 2013-2015, I was a member of the Exoplanet Probe Science and Technology Definition Teams. The goal was to study concepts for relatively near-term, medium-sized space telescopes aimed at direct observations of exoplanets and planet-forming disks. I was on the External Occulter team, which studied a concept that uses a free-flying starshade to block out bright stars and see the faint planets or disks around them.
