Dr. Lei Raymond Cao is a Professor and the Program Director of the Nuclear Engineering Program at The Ohio State University (OSU). He also serves as the Director of OSU-Nuclear Reactor Lab. Dr. Cao received his B.S. degree in experimental nuclear physics from Lanzhou University (1994), MS in nuclear physics from CIAE (2002), and Ph.D. from nuclear and radiological engineering program at the University of Texas at Austin (2007). Prior to joining OSU, Dr. Cao was a research associate at Positron Emission Tomography lab at Harvard Medical School and then at the Center for Neutron Research, National Institute of Standards and Technology (NIST) at Maryland. Dr. Cao's major research interests focus on nuclear instrumentation and sensor, in-pile instrumentation, radiation effects, and nuclear analytical technologies. Dr. Cao has published over 100 peer-reviewed journal articles and ~ 50 conference proceedings. Dr. Cao is on the executive committee of the Isotope and Radiation Division (IRD) at the American Nuclear Society and also served as the IRD chair during 2015-2016. He is the Associate Editor for IEEE Transactions on Nuclear Science and on the editorial board of Nuclear Science and Engineering.
