Hello, I'm Mingming Xu (Mindy).

I am a third-year Ph.D. student in the School of Mathematical and Statistical Sciences at Clemson University, advised by Prof. Hao Hu. My research focuses on using semidefinite programming (SDP) to solve combinatorial optimization problems.

Outside of research, I am a big fan of art exhibitions and musicals. I also love grabbing a good movie and staying active on the court. Always happy to chat about math, musicals, or anything in between. Feel free to reach out!
