About me

I am an incoming Tenure-track Assistant Professor at School of Intelligence Science and Technology, Nanjing University. Previously, I was a Shuimu Postdoc Researcher at Department of Automation, Tsinghua University, collaborating with Prof. Yebin Liu. I also worked closely with Prof. Yichang Jia (Department of Medicine) on ALS disease modeling. From 2017 to 2024, I obtained my Ph.D. degree in Automation from Tsinghua University, under the supervision of Prof. Yebin Liu.

In Nanjing University, I will continue my research on Embodied 3D Vision and AI4Science, collaborating with Prof. Xun Cao. Specifically, I will design 3D Vision / Embodied AI algorithms for both humans and animals, and apply them to agriculture, neuroscience and medicine. I am actively recruiting prospective PhD students, master's students, and research interns who are passionate about Embodied 3D Vision and AI4Science. I am also open to academic and industrial collaborations. Please feel free to reach out (to my email).

Positions Available:

2027 Fall Ph.D. students (2-4), 2027 Fall Master students (>=1)
