Biography

Thomas S. Duffy is a Professor in the Department of Geosciences at Princeton University, where he chairs the department and leads the High-Pressure Mineral Physics Laboratory. His research primarily focuses on understanding the large-scale behavior of Earth and planetary materials under extreme conditions of pressure and temperature. Duffy employs a variety of experimental techniques, including static compression with diamond anvil cells, optical spectroscopy, and x-ray techniques to investigate the crystal structures, phase relations, and elasticity of materials subjected to conditions that exceed those found at the center of the Earth. Furthermore, he utilizes high-powered lasers and gas guns for dynamic compression experiments to examine material properties for very short durations on the order of nanoseconds to microseconds using x-ray diffraction and laser interferometry. Key research interests include high pressure, exoplanets, shock compression, and the behavior of geological materials under extreme conditions.
