Jeff Kauffman is an associate professor in the Department of Mechanical and Aerospace Engineering at UCF. He earned doctoral and master's degrees in aerospace engineering at Penn State and a bachelor's degree in engineering and applied science/aeronautics at Caltech. Kauffman conducts broad research in the areas of structural dynamics and adaptive structures, with particular focus on multifunctional and energy-efficient structures for vibration reduction, energy harvesting and structural morphing. His research has been funded by several government agencies and industry partners.
