Dr. Yu joined NREL in August 2009 as a postdoctoral researcher in the Solid State Theory Team. He received his Ph.D. in physics from North Carolina State University in 2009 under the supervision of Dr. Jerry Bernholc. His research in computational materials science focuses on first principles (DFT) studies of defect, electronic, optical, and dielectric properties of real materials. Currently he works on the computational design and theoretical modeling of renewable energy materials for the Center of Inverse Design, a DOE Energy Frontier Research Center (EFRC).
