My current work as a Doherty Associate Research Scientist at Lamont-Doherty Earth Observatory focuses on the linkage between extensional tectonics and ice sheet dynamics on the Antarctic continent. The optimum approach to study processes linking ice sheet dynamics and geological structures is the analysis of integrated airborne geophysical data consisting of gravity, magnetics, laser altimetry and ice penetrating radar. Four different regions in Antarctica are currently the target for my studies:
