BIOGRAPHY:

I use laboratory experiments to investigate the feedback between deformation processes and material properties. My work includes use of microstructural tools (electron microscopy, mass spectrometry, and FT-IR spectroscopy) and in situ measurements (ultrasonic wave analyses, permeability, stress, and strain) to derive mathematical models of deformation phenomenon. My interests include reaction-driven cracking during carbon mineralization of rocks, hydrolytic weakening in minerals, and shock induced deformation of ceramics.
