Dr. Samarth is Downsbrough Department Head and Professor of Physics at the Pennsylvania State University (PSU). From 1992-1998 he was Assistant Professor of Physics at PSU, and was promoted to Associate Professor in 1998 and to Professor in 2001. He performed his post-doctoral research as a Research Associate and Assistant Faculty Fellow at the University of Notre Dame under Professor Jacek Furdyna (1986-1992). He received this Ph.D. in Physics from Purdue University, also under the direction of Professor Jacek Furdyna (1980-1986). He is a Fellow of the American Physical Society and Fellow of the American Association for the Advancement of Science, a recipient of PSU’s Faculty Scholar Medal in the Physical Sciences and received an Outstanding Physics Alumnus Award from Purdue University. Dr. Samarth has pioneered the epitaxial growth and nanopatterning of a variety of spin-based heterostructures based upon both conventional and magnetic semiconductors and ferromagnetic metals, resulting in fundamental advances in semiconductor spintronics [1-6], frustrated magnetic arrays [7,8] and topological insulators [9,10,11]. He has published 225 papers with about 8000 citations and has an h-index of 45.
