    Professional Biography

    Professor Hofmann received her Ph.D. in Geochemistry.  Her dissertation explored the relationship between kinetic and thermodynamic driving forces and the sub-micron-scale distribution of cationic impurities within the crystal lattices of two petrologically significant minerals.  Professor Hofmann then spent the following three years as a postdoctoral fellow at Lawrence Berkeley National Laboratory where, using a combination of experimental and computational techniques, she investigated molecular-scale mechanisms responsible for the separation of isotopes in solution. During this time, she also served as a visiting faculty member in the Department of Earth & Planetary Sciences at UC Berkeley.
