Go in the only glass door facing Atherton St. Once in the lobby, go to the first office to your right. * Office hours for the Fall 2016 semester: 9:00-10:00 A.M. Tues. and Thurs., or by appointment. ==== Education ==== * B.S. (Mechanical Engineering), Lehigh University * M.S., PhD. (Engineering Mechanics), Virginia Polytechnic Institute and State University ==== Research ==== My main research interests are the manufacturing, performance, evaluation, and mechanics of fiber reinforced composite materials. Application areas include fixed and rotary wing aircraft, civil structures, and energy conversion/storage. My recent projects projects include: * Nanofillers for multifunctional structural composites * Characterization and modeling of externally bonded composite (FRP) reinforcements for concrete under elevated temperature and sustained loads * Flexible matrix composites for highly deformable, active, and morphing structures * Optimal design of composite flywheel energy storage rims * 3D printed composite materials * Structural batteries for automotive applications ==== Titles of Representative Publications ==== - Jeong, Y., Lopez, M.
