Hi, I’m Xian Yu (于弦 in Chinese). I joined the Department of Integrated Systems Engineering at The Ohio State University as an Assistant Professor in August 2022. I completed my Ph.D. in Operations Research at the University of Michigan in April 2022, where I was advised by Prof. Siqian Shen. My research interests are in large-scale sequential decision-making and optimization under uncertainty, where my research focuses on utilizing special problem structures and deriving efficient algorithms for solving related problems arising in smart transportation, logistics, and supply chain management.
