Zichao (Wendy) Di is a computational mathematician at Argonne National Lab with a joint appointment between Mathematics and Computer Science Division and X-ray Science Division. She joined Argonne as a postdoctoral associate in November 2013. Prior to this, she received her Ph.D. in applied mathematics from George Mason University in 2013, and B.S. in Information and Computing Science from Dalian University of Technology in China in 2008.
Wendy’s research focus is on generalization of multilevel methods for solving optimization problems ranging from vector quantization, optimal control to inverse problems, as well as information integration and multimodal data analysis especially from x-ray data sources. More broadly, her work is on the development of mathematical models and efficient optimization methods to tackle challenging applications arising from real-life phenomena.
