Biography
I am an incoming PhD student in Mathematics at UBC’s Okanagan Campus, supervised by Dr. Warren Hare and Dr. Amy Wiebe. Previously, I finished my MSc in Mathematics at UBC and BSc in Hua Luogeng Mathematics Class (Mathematics and Applied Mathematics) at Beihang University.
My research interests include derivative-free optimization, numerical optimization, and numerical analysis. Also, I’m interested in computer programming and algorithms.
