About Me

I am a final-year Ph.D. candidate in Operations Research at Cornell University, advised by Professor Huseyin Topaloglu at Cornell Tech. I obtained my B.E. in Automation at Tsinghua University in 2018, with a minor in Statistics.

I am broadly interested in developing efficient and provably good algorithms for online and offline decision problems with applications in revenue management, pricing, inventory control, online marketplaces and the sharing economy.
