Todd A. Palmer holds a joint appointment as a Professor of Engineering Science and Mechanics and Materials Science and Engineering and is the director of the Center for Innovative Sintered Products in the Department of Engineering Science and Mechanics at Penn State. Prior to assuming his current position, he was with the Applied Research Laboratory at Penn State from 2007 to 2017, where he rose to the rank of Senior Scientist. From 2000 to 2007, he was at Lawrence Livermore National Laboratory, Livermore, Calif., where he was a metallurgist in the Materials Science and Technology Division.
Our research lies at the nexus of materials processing, microstructural characterization, and materials properties and performance critical to the development of advanced manufacturing processes. Specific research areas include high energy density welding and joining, additive manufacturing, and particulate material processing, primarily in metallic material systems. The combination of these different fields underlies many emerging fabrication technologies and allows us to work at the frontiers of metal-based additive manufacturing, particulate materials processing, and computational modeling. Working in these different areas requires a highly interdisciplinary approach and allows us to work in close collaboration with a wide range of stakeholders across academia, government, and industry and take advantage of advanced characterization tools for the in situ study of these complex materials processing operations.
