Dr. Zumbrunnen is a Fellow of the American Society of Mechanical Engineers and a registered professional engineer. He first proposed that micro- and nanostructured plastic materials can be formed controllably by inducing chaotic advection in multi-component melts. Smart blending machinery, novel materials, and manufacturing processes resulted and several patents have been awarded. He is a recipient of the Presidential Faculty Fellow Award from The White House and National Science Foundation. He has served as an associate technical editor for the ASME Journal of Heat Transfer and on society technical committees. Dr. Zumbrunnen was a founding research thrust leader for a NSF Engineering Research Center and has been an advocate for multidisciplinary research. He teaches courses focusing on heat and mass transfer, nuclear energy, renewable energy sources, and engineering design. He was previously a nuclear-trained US naval officer in the nuclear submarine service and worked in a nuclear energy services company.
