Biography
Research Interests
My research focuses on the development of new processes for the additive manufacturing of metals and ceramics by understanding reactions driven by electron, laser, and ion beams. I have particular interest in the design and implementation of in situ characterization techniques using high-speed optical imaging, electron microscopy, and various synchrotron X-ray capabilities to probe the fundamental mechanisms underlying 3D printing and nanofabrication processes. A significant portion of my scientific research has been in collaboration with industrial partners to understand the science underpinning materials processing techniques and incorporating these findings into new technologies.
