I am an assistant professor of Astronomy in the Caltech Department of Astrophysics. I received my Ph.D. and M.S. in Astronomy from UC Berkeley, and my B.S. in physics from the University of Missouri-Rolla (now known as the Missouri University of Science and Technology).


My primary research focus is on the detection and characterization of exoplanets. For more details check out my research pages:


Planet detection

Planet characterization using transits


I've been fortunate to have my research featured in several popular science publications:


Planets of Massive, Retired A Stars (Sky & Telescope)

Heftier Stars More Likely To Host Planets (New Scientist)

Hot, Heavy and Eccentric (Sky & Telescope)
