| Donald J. Weidner
A.B., Harvard University, 1967
Ph.D., Massachusetts Institute of Technology, 1972
Faculty member at Stony Brook since 1972
Professor Weidner's research interests focus on mineral physics and seismology. The ultimate goals are to combine these areas to help define the physical and chemical state as well as the dynamic processes of the Earth's mantle and crust.
