Thomas S. Duffy of the Seismological Laboratory at the California Institute of Technology has received the Mineral Physics Student Award for 1991. This cash award is given to a student within the field of mineral physics who shows unusual promise, as evidenced by letters of support and material written by the student.
In his graduate work with Tom Ahrens at Caltech, Duffy measures sonic velocities in materials under high pressure and temperature conditions. His papers have covered constraints on mantle mineralogy by measurements of seismic velocities in minerals, elasticity measurements on enstatite, and measurements of sound speed under shock. Tom's nomination describes Duffy as “an outstanding young mineral physicist who is very smart and has a great deal of drive and ambition.”
