Hi! Welcome to my website. I’m Yushan Qu, a third-year PhD student in Industrial and Operations Engineering at the University of Michigan, working under the guidance of Professor Jon Lee. My research focuses on combinatorial optimization and discrete optimization. I’m passionate about exploring complex mathematical problems and developing innovative solutions in optimization theory. My email address is yushanqu@umich.edu. Thanks for visiting!
