My current research is focussed on the detection and characterization of planets around nearby stars. This work involves using high resolution spectroscopy on large telescopes to obtain meter/second precision radial velocities, through which planets can be detected, sensing the reflex barycentric motion of their host star. I also do a lot if instrumentation development in support of this research. I am in the latter stages of commissioning a 2.4-m Automated Planet Finder telescope atop Mt. Hamilton, and am also working on an early-light spectrometer called MTHR for the Thirty-Meter Telescope.
