Mechanical behavior of nanostructured metals and additively manufactured materials, laser-materials interactions, materials under extreme conditions, fusion science and technology, lithium-ion batteries and supercapacitors.

##### RESEARCH AND INTERESTS

Our group’s research interests bridge among the synthesis of nanostructured materials, additive manufacturing, and understanding the underlying mechanisms that control the mechanical behavior of various advanced materials (metals and alloys, carbon-based materials, 2D materials, and porous materials). We apply in situ characterization techniques (e.g., in situ synchrotron x-ray diffraction, computed tomography, transmission electron microscopy) to probe how the defects interact with surfaces or interfaces. Our research is focused on achieving high-performance structural materials via microstructure engineering. Occasionally, we are also interested in their functional properties such as electrical conductivity, corrosion resistance, catalytic activities, and electrochemical energy storage capacity. Our experimental work is more often coupled with computer modeling to help deepen our understanding of structure-property relationships. In addition to materials science, we welcome students with a strong background in applied physics, chemistry, and mechanical engineering to join the team.
