Russell J. Hemley's research explores the chemistry of materials over a broad range of thermodynamic conditions from low to very high pressures. He began his research career in molecular spectroscopy and electronic structure theory. An interest in the effects of high pressures on materials led him to the Geophysical Laboratory of the Carnegie...
