James Head’s research centers on the study of the processes that form and modify the surfaces, crusts, and lithospheres of planets, how these processes vary with time, and how such processes interact to produce the historical record preserved on the planets.  Comparative planetology, the themes of planetary evolution, and application of these to the study of early Earth history are also of interest. He is particularly interested in volcanism and tectonism, having done fieldwork on active volcanoes in Hawaii and at Mount St. Helens. From the Series:Danz Lecture Series
