Research Interests
Small and macro-scale mechanical testing in extreme environments (hydrogen and cryogenic influences on materials), MEMS and Chip-scale property measurements. Design and development of instruments, experiments, and instrumentation for systems from 4 K to ambient temperature regimes and extreme environments. Collaborations and mentorships with graduate, post doctoral, and guest researchers from institutions globally (more than three dozen to date).
