Southwest Research Institute (2004 - present)

New Horizons responsibilities include Deputy Project Scientist since 2013, Co-Investigator on the Science Team since 2007, Project Manager for the Ralph instrument since 2006 and currently Deputy PI for the Ralph instrument, SwRI-PI for New Horizons (2007 - 2008), Director of the Office of the PI effective 2008, Education and Public Outreach Liaison to the Science Team 2008 - 2014.

Research interests include near-IR spectroscopy to study planetary surfaces and stellar occultation observations to investigate planetary atmospheres.

Lowell Observatory (1996-2004)

Studied the rings of Uranus and Saturn using stellar occultation observations and STIS spectra.  Measured the mass ratio of Charon to Pluto using HST Fine Guidance Sensors. Predicted the shadow path for the July 1997 stellar occultation by Triton.

Massachusetts Institute of Technology (1991-1996)

Established Triton’s atmospheric structure using occultation observations, modeled the near nucleus environment on 2060 Chiron, predicted occultation shadow paths for small-body events.

Jet Propulsion Laboratory (1989-1991)

Performed orbit determination analysis for the Cassini, CRAF and Lunar Observer missions.
