Mark G. Allen  Mark G. Allen is a professor specializing in microfabrication, nanotechnology, and microelectromechanical systems at the University of Pennsylvania, where he is currently Alfred Fitler Moore Professor of Electrical and Systems Engineering Director of the Singh Center for Nanotechnology, and leader of the Microsensor and Microactuator Research Group. Prior to his joining the University of Pennsylvania in 2013, he was with the Georgia Institute of Technology, where he was Regents' Professor of Electrical and Computer Engineering and the J.M. Pettit Professor in Microelectronics. While at Georgia Tech, he also held multiple administrative positions, including Senior Vice Provost for Research and Innovation; Acting Director of the Georgia Electronic Design Center; and Inaugural Executive Director of Georgia Tech's Institute for Electronics and Nanotechnology. He was editor in chief of the "Journal of Micromechanics and Microengineering (JMM)", and currently serves on the editorial board of JMM as well as the journal Microsystems and Nanoengineering (Nature Publishing Group). Allen received a BA in chemistry, a BSE in chemical engineering and a BSE in electrical engineering from the University of Pennsylvania, and an MS in chemical engineering and a Ph.D. (1989) in microelectronic materials from the Massachusetts Institute of Technology. After completing his education in 1989, Allen became a member of the faculty of the School of Electrical and Computer Engineering of the Georgia Institute of Technology, ultimately holding the rank of Regents' Professor and the J.M. Pettit Professorship in Microelectronics. In 2013 he joined the University of Pennsylvania faculty as the Alfred Fitler Moore Professor of Electrical and Systems Engineering, as well as being named the founding director of the Singh Center for Nanotechnology at Penn. Professor Allen’s current research interests are in the field of microfabrication and nanofabrication technology, with emphasis on new approaches to fabricate devices with characteristic lengths in the micro- to nanoscale from both silicon and non-silicon materials. He has published approximately 450 journal articles and conference proceedings, and holds nearly 60 patents (Google Scholar h‐index of 73, with 23,000+ citations). He has graduated approximately 50 Ph.D. students in various disciplines, including electrical and computer engineering; chemical and biomolecular engineering; mechanical engineering; materials science; polymer, textile, and fiber engineering; and biomedical engineering. Approximately one-third of his former Ph.D. students hold faculty positions around the world.
