He works on the fundamental problem of observing, understanding, and predicting the configuration and evolution of ice sheet boundary conditions using ice penetrating radar sounding data. Before coming to Stanford he worked as a radar systems engineer with the Jet Propulsion Laboratory at the California Institute of Technology. He is also a science team member and co-investigator on the REASON (Radar for Europa Assessment and Sounding: Ocean to Near-Surface) radar sounder on NASA’s Europa Clipper mission and is an active collaborator on the RIME (Radar for Icy Moon Exploration) radar sounder for EASA’s JUICE mission to Ganymede. He received his PhD in geophysics from the University of Texas at Austin where he served as the lead radar engineer and operator during three Antarctic field seasons with the ICECAP and Operation Ice-Bridge projects.
