Research Interest

My laboratory's efforts are directed towards utilizing a combination of materials synthesis/characterization and high pressure measurements to advance our understanding of novel and potentially useful electronic and magnetic materials. The pressures employed span the range from kilobars (the pressure at the bottom of the ocean) to megabars (nearing the pressure at the core of the earth). In particular, I am interested in understanding the conditions under which unconventional and/or high temperature superconducting states form.
