High-pressure, high-temperature physics. I study phase diagrams, metastability, and the kinetics of transitions in pure elements by studying crystal structure and optical and electronic properties of materials at high pressure. I perform diffraction measurements with rapidly varying pressure/temperature conditions to study the effects of kinetics and to study entire phase diagrams with single-shot experiments.
