Although located far from the main centers of human civilization, the polar atmosphere and oceans have strong global connections and therefore directly affect climate, landscape evolution, the global biosphere and human society. Over geologic time scales, Antarctic geodynamic processes are a major influence on ice sheet dynamics and global environmental change, which affects current and long-term, large-scale sea-level change.
My research at Lamont links solid Earth geophysics and glaciology, providing unique research opportunities. I use integrated sets of aerogeophysical data, including gravity, magnetics, ice-penetrating radar, and laser altimeter measurements, to study physical processes linking tectonics, ice sheet dynamics and life in extreme environments, such as subglacial lakes.
A description of my research interests can be found on my homepage:
