Thomas Duffy has been a professor in the Department of Geosciences at Princeton University since 1997. His research interests broadly focus on mineralogy and mineral physics with an emphasis on the properties of geological materials at high pressures with applications to understanding the structure and dynamics of the Earth and other planets. Specific areas of research include the mineralogy of the Earth’s upper and lower mantles, shock compression of geological materials, and the use of novel laser compression techniques to achieve ultrahigh pressures relevant to the interiors of large exoplanets. His work explores crystal structures, equations of state, phase transitions, and elastic properties of all types of Earth and planetary materials.
Thomas received his Ph.D. from the California Institute of Technology in 1992. He joined Princeton after postdoctoral and research scientist positions at the Carnegie Institution for Science and the University of Chicago. He is currently Chair of the Geosciences Department at Princeton, an affiliated faculty at the Princeton Materials Institute, and a member of the Academic Freedom Alliance. Recently, he led an effort to develop a national plan for the management and operation of synchrotron-hosted analytical capabilities for Earth sciences research. He is a fellow of the American Geophysical Union, the Mineralogical Society of America, and the David and Lucile Packard Foundation.
