Bogdan-Ioan Popa is an assistant professor in the Department of Mechanical Engineering. He earned his PhD and M.S in Electrical and Computer Engineering from Duke University as well as a B.S from the Polytechnic University of Bucharest. Before coming to the University of Michigan, Popa held various research positions at Duke University.
Design, optimization, and dynamics of new generations of engineered materials (metamaterials) that allow improved control over the propagation of acoustic, elastic and electromagnetic waves with applications in biomedical engineering, telecommunications, aero- and underwater acoustics; noise control; smart materials; mechatronics.
