Tevis D. B. Jacobs received the B.Sc. degree, with majors in mechanical engineering and materials science and engineering, from the University of Pennsylvania, Philadelphia, in 2003, the M.Phil. degree in computer modeling of materials from Churchill College, University of Cambridge, Cambridge, U.K., in 2004, and the M.Sc. degree in materials science from Stanford University, Stanford, CA, in 2006. He is currently working toward the Ph.D. degree in materials science at the University of Pennsylvania. He worked for two years as an Engineer at Animas Corporation, a Johnson & Johnson company. His interest lies in the fundamental physics of sliding-induced wear, particularly in silicon- and carbon-based materials. Specifically, he is using atomic force microscopy and in situ transmission electron microscopy to carry out experiments and using principles from chemical reaction kinetics to analyze results.
