Hello! Here is Xiuqiang HE (何秀强). I am a Research Assistant Professor at Tsinghua University. Before that, I was a Postdoctoral Researcher at ETH Zürich, working at the Automatic Control Laboratory with Prof. Florian Dörfler from 2021 to 2024, and then a Senior Scientist from 2024 to 2025. I received my Ph.D. degree in Control Science and Engineering from Tsinghua University in 2021, supervised by Prof. Hua Geng, and my B.S. degree from Tsinghua University in 2016. You can find further details in my CV.
