I'm an experimental astrophysicist working in the field of exoplanet imaging. The goals of my research group are detection and characterization of planets around other stars, and we pursue these goals by building, developing, and using new instruments.

Previously to joining the faculty of the IfA, I was an optical engineer at NASA's Jet Propulsion Lab, working on developing the Roman Coronagraph, formation flying for the Starshade mission, and wavefront sensing for large ground-based telescopes. I also led small a team in developing new post-processing algorithms for exoplanet imaging.

I received a PhD in astrophysics from Caltech and did my undergraduate work at Columbia.

Research areas

My group's research is a mix of science and engineering, on the ground and in space, mainly towards the goal of imaging and characterizing extrasolar planets.

High contrast imaging of circumstellar regions

Detector development and characterization

Wavefront control for extreme adaptive optics

Exoplanet image processing algorithms

Spacecraft formation flying
