About Me

I am a postdoctoral research fellow at Hua Loo-Keng Center for Mathematical Sciences, AMSS,CAS in Beijing, working with Prof. Lihong Zhi and Prof. Ke Ye. I was previously a research fellow at CNRS@CREATE in Singapore from August 2023 to August 2024 working with Prof. Victor Magron and Prof. Jean-Bernard Lasserre. I received my doctor's degree of mathematics under the supervision of Prof. Lihong Zhi at AMSS-CAS in July 2023. I received my Bachelor's degree from Sichuan University in 2018, under the guidance of Prof. Weinian Zhang.

I'm working on robust polynomial optimization and its applications in neural network verification.
