Arjun G. Yodh is the James M. Skinner Professor of Science and Chair of the Department of Physics and Astronomy at the University of Pennsylvania. Until recently he was Director (2009-2020) of The Laboratory for Research on the Structure of Matter (LRSM) and its NSF-supported Materials Science and Engineering Center (MRSEC). His home department is Physics & Astronomy. Yodh graduated from Cornell University (1981) with a BSc in Applied & Engineering Physics; he obtained his PhD from Harvard (1986) under the guidance of Tom Mossberg, and he then spent two years at AT&T Bell Laboratories as a post-doc working with Steve Chu and Harry Tom. Yodh joined the faculty at Penn in 1988, where he has remained for his entire career. In addition to mentoring >100 PhD students and post-doctoral associates during his career, Yodh has made significant contributions to education, outreach and diversity at Penn (broadly defined). As LRSM Director, for example, he played a major role creating and implementing STEM education and outreach programs that target people at all levels. Notable among these efforts are LRSM partnerships with the University of Puerto Rico (PREM, Co-Director) and the Girard College of Philadelphia, as well as research experience programs for undergraduates (REU, Site-grant PI), high school students (PSSI), and high school teachers (RET) in the Philadelphia region and beyond.
