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

Selected Research Projects
I'm participating in a Key Science Project for the Large Binocular Telescope Interferometer: the “HOSTS” survey, which is a sensitive survey of warm interplanetary dust around nearby stars. Such dust — similar to the Solar System's zodiacal dust — comes from unseen asteroids and comets orbiting the stars. It is one of the important challenges for eventually directly imaging rocky terrestrial planets around other stars, since a large amount of dust can hide the planets.

I'm also involved in planning for future space telescopes aimed at exoplanets and planet formation studies. One new activity is ...

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