K.T. Ramesh

Director, HEMI

K.T. Ramesh is the Director of the Hopkins Extreme Materials Institute (HEMI). He is also the Alonzo G. Decker Jr. Professor of Science and Engineering at Johns Hopkins University. His research interests are in high strain rate behavior and dynamic failure of materials, nanostructured materials, injury biomechanics and planetary scale impact problems. Prof. Ramesh received his doctorate from Brown University in 1987 and worked briefly as a postdoctoral fellow at the University of California, San Diego. He joined the Department of Mechanical Engineering at Johns Hopkins in 1988 and served as the Department Chair from 1999-2002. He has served as founding Director of HEMI since 2012. He has published one book (Nanomaterials: Mechanics and Mechanisms; Springer) and threatens to write another. He is an avid amateur astronomer.

Sometimes the best way to make something better is to break it.
