About me

I am an Assistant Professor at the Hong Kong University of Science and Technology (HKUST). Previously, I was a postdoctoral researcher at Southern University of Science and Technology (SUSTech), hosted by Prof. Kailiang Wu at the Department of Mathematics. I received my Bachelor degrees in Aerospace Engineering and Mathematics from Tsinghua University in 2016, followed by a Diplôme d'Ingénieur and a PhD degree from Mines Paris – Université PSL. My PhD supervisors are Prof. Elie Hachem and Dr. Jonathan Viquerat.
