Four different artist’s impressions of known extrasolar planets.  Some planets are gas giants orbiting very close to their host stars (top left, top right), while others are smaller and may be terrestrial or even earth-like (lower left, lower right).  Image credits (clockwise from top left): HD 189733, ESA/C. Carreau; HD 189733, ESA, NASA, & G. Tinetti; Gl 581, ESO; Gl 667, ESO.

I am a professor in the Division of Geological and Planetary Sciences at the California Institute of Technology.  My group is working on topics including the physics and chemistry of exoplanetary atmospheres, planet formation and migration, and the search for new low-mass eclipsing planetary systems.
