Yiyang Sun received his Bachelor Degree from Jilin University, China, in 1996 and Master Degree from Xiamen University, China, in 1999. He joined the Surface Science Lab at the National University of Singapore (NUS) to pursue his Ph.D., where he was supervised by Professor Andrew Wee and Professor Alfred Huan studying the structures of stepped metal surfaces involving both experimental (LEED, STM) and computational techniques (Quantitative LEED analysis and first-principles calculations). He received his Ph.D. in 2004 at which time he accepted a Research Fellow position working with Professor Yuan Ping Feng (NUS) for the next two years. Currently, Dr. Sun’s research focus has centered around Density Functional Theory (DFT) based calculations on materials properties, while still maintaining close collaborations with experimentalists. He has also studied surface reconstructions, nanocluster formation on semiconductor surfaces, and defect formation in high-k materials.

His current research interests are:

1. DFT-based calculations on the van der Waals interactions.
