Sridhar is a Professor in the Department of Geosciences and an associate of the Earth and Environmental Sciences Institute (EESI). Sridhar teaches geophysics and glaciology and conducts research in as many cold places as he can convince folks to let him visit. So far he has done most of his fieldwork in West Antarctica and Greenland, with the occasional foray to Norway and Iceland. His interests involve using geophysical tools (seismology, ice penetrating radar, and GPS) to work out how and why glaciers flow in the ways they do. He was hooked on glaciology on his first trip to Antarctica and is still delighted every time he can stand on a glacier.
