Exoplanet science and technology

Understanding the formation of planets around other stars is a major goal of modern astronomy and may give insight into age-old questions: "where do we come from?" and "are we alone?" Scientists probe the circumstellar environment by analyzing the scattered, reflected, and emitted light from disks and planets. However, the light from the star is often billions of times brighter making them difficult to image.

My research focuses on enabling the direct detection of exoplanets at small angular separation from their stars.
