I am an experimental astrophysicist. My research interests are the detection and characterization of extrasolar planets and their host stars, and I pursue these goals by building, developing, and using new instruments. I primarily work in the field of high-contrast imaging and also have experience with radial velocity exoplanet instrumentation.
Previously to joining the faculty of the IfA, I was an optical engineer at NASA’s Jet Propulsion Lab, working on developing the WFIRST Coronagraph camera, formation flying sensors 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.

My research is located at the intersection of astronomy, optics, and data analysis, working towards the goal of taking pictures of planets around other stars. Exoplanet imaging is a technically challenging field, and as such, a large fraction of my time is building and working with new instrumentation. Particular interests include wavefront sensing and control for ground based telescopes, data analysis and post-processing algorithms for exoplanet imaging, and developing the next generations of detectors for ground and space-based instruments. My group makes regular use of the largest telescopes in the world for observing planets and disks.
Interested students are welcome to contact me about potentially working together.
