Research Interests

My research is aimed at understanding the stability of the West Antarctic Ice Sheet and the rapidly-flowing ice streams that drain the interior of the ice sheet. I use seismic techniques (identical to those used in the Petroleum Exploration industry) to determine englacial and subglacial properties. In addition, I use broadband (earthquake) seismic techniques to determine the deeper structure of the Antarctic crust and mantle.
