David J. Hilton, Ph.D.

Assistant Professor of Physics, Electrical and Computer Engineering

PhD, Applied Physics, Cornell University, 2002

Website: Ultrafast Spectroscopy and Quantum Materials Lab

Research Interests

Our interests include insulator-to-metal transitions in vanadium dioxide, superconductivity, terahertz spectroscopy of interstellar ices, Quantum Hall systems, and wide band gap semiconductors. We utilize a number of electrical, time-integrated optical, and ultrafast optical spectroscopic techniques to study the ground state and optically perturbed materials.
