Frances Hellman received her B.A. in Physics at Dartmouth College in 1978 and her Ph.D. in Applied Physics at Stanford University in 1985.

Her current research includes effects of spin on transport and tunneling, including studies of amorphous magnetic semiconductors and spin injection from ferromagnets into Si; finite size effects on magnetic and thermodynamic properties; formation of perpendicular magnetic anisotropy in magnetic thin films and effects of the vapor-deposition growth process on the structure of thin film amorphous and crystalline materials. She and her research group also have an extensive effort in development of calorimetry for thin films, small bulk samples, and nano-scale biological systems. They use Si-microfabrication techniques to create membrane-based micro/nanocalorimeters that allow us to measure films weighing micrograms or less from 1-500K and in magnetic fields at present to 8T. They are working with researchers at the national high magnetic field lab to extend the magnetic field range to 45T in steady state and 100T in pulsed fields, and the temperature range to 0.3K.
