After obtaining his Ph.D. in 1996, Dr. Yu joined Los Alamos National Laboratory as a Director-funded postdoctoral fellow, working on electrical transport in conjugated polymers and charge-spin separation in transition-metal oxides. Additionally, he spent a few years at Iowa State University and University of Iowa, working on electron transfer in biological systems and spin-dependent electrical transport in semiconductors and devices before he joined SRI International in 2003. At SRI International, Dr. Yu studied electronic, (nonlinear) optical, and transport properties of bulk and nanomaterials for novel applications. Dr. Zhi-Gang Yu joined the Applied Sciences Laboratory in 2014.
