I'm an experimental astrophysicist working in the field of exoplanet imaging. The goals of my research group are the detection and characterization of planets around other stars, which we pursue by building, developing, and using new instruments. Our main research efforts focus on developing infrared detectors and instrument concepts for the Habitable Worlds Observatory, adaptive optics instrumentation for large ground-based telescopes like Keck and Subaru, and observing disks and planets using the most advanced ground-based telescopes in the world.

Prior to joining the faculty of the UC Berkeley, I was an astronomer at the Institute for Astronomy in Hilo, Hawai`i and an optical engineer at NASA's Jet Propulsion Lab. I received a PhD in astrophysics from Caltech and did my undergraduate studies at Columbia.
