Biography

Materials scientist with expertise in microscale deformation, irradiation effects, and corrosion behavior of structural alloys for nuclear and energy applications. Skilled in advanced microscopy (SEM, FIB, TEM, HR-EBSD), mechanical testing (high-temperature, fatigue, creep, HR-DIC), in-situ experimentation, and crystal plasticity modeling. Demonstrated ability to develop process-structure-property relationships, with a strong record of first-author publications in premier journals. Committed to advancing materials performance in extreme environments.
