BrianLightI am a Ph.D. student working in HiPSEC under Dr. Ravhi Kumar and Dr. Andrew Cornelius. My recent work is focused primarily on high-pressure X-ray diffraction measurements at HPCAT in sectors 16 of the Advanced Photon Source at Argonne National Laboratory.  I am beginning a new project on topological insulators that will involve high-pressure measurements using a variety of techniques including X-Ray diffraction, resistivity, magnetic susceptibility and Hall effect. Some of these techniques will require experimental apparatus development.

Previously, I worked on heat capacity and electrical transport measurements at low temperatures. My master’s thesis was done on the heavy fermion antiferromagnet CeRhIn5.
