Uwe Paul Erich Thumm is a German-American physicist with research interests in atomic, molecular, and optical physics and nanoscience. A distinguished physics professor at Kansas State University and the J. R. Macdonald Laboratory in Manhattan, Kansas his research team investigates the ultrafast dynamics of electrons and molecular fragments in laser-matter and particle-matter interactions, highly-charged-ion physics, electron–atom collisions, and plasmonic nanostructures. He is a Fellow of the American Physical Society and recipient of several awards, including the Senior Research Award of the Alexander von Humboldt Foundation.
