Dr. Suveen Mathaudhu joined the Pacific Northwest National Laboratory as a joint-appointee from the University of California, Riverside, Mechanical Engineering Department and Materials Science and Engineering Program. He currently serves as Thrust Lead for Nanocomposites within the Materials Simulation and Synthesis Across Scales (MS^3) laboratory-level initiative. This thrust focuses on the fundamental design and scale up of thermally-stable advanced functional and structural materials. Dr. Mathaudhu's research background centers on the synthesis and processing of advanced nanostructrured metallic alloys and composites. Prior to joining PNNL/UCR, he served as a Program Manager for the Synthesis and Processing program at the U.S. Army Research Office where he initiated a broad range of basic-research programs focusing on advanced structural and armor materials. Before this position, he was a Materials Engineer at the U.S. Army Research Laboratory, Weapons and Materials Research Directorate where he began his career as a ORISE Post-doctoral Fellow.

Dr. Mathaudhu has over 70 peer-reviewed publications, and 30 Invited lectures on topics ranging from advanced materials, to STEM education to career development. He is a Fellow of ASM International, and in 2015 was honored with the American Association of Engineering Society's Norm Augustine Award for Outstanding Achievement in Engineering Communication. He holds a B.S.E. degree from Walla Walla University, and M.S. and Ph.D. degrees from Texas A&M University, all in Mechanical Engineering.
