Biography

I am a beamline scientist at HPCAT, Sector 16 of the Advanced Photon Source, responsible for developing novel high-pressure x-ray techniques, conducting original research, and supporting users at the beamlines. My current research focuses on developing new instrumental platforms for high-resolution x-ray microscopy and time-resolved experiments for high-pressure sciences.
