Biography

I am currently a researcher at the Shenzhen Institute of Artificial Intelligence and Robotics for Society and an adjunct assistant professor at the School of Science and Engineering, the Chinese University of Hong Kong, Shenzhen. I got my Ph.D. in the Graduate School of Information Sciences, Tohoku University, supervised by Prof. Takayuki Okatani in 2020. My current research interest lies at the intersection of artificial intelligence and robotics, mainly including multi-sensory learning, lifelong learning, 3D vision, robot perception, and multi-robot perception.

Please drop me an email if you are interested in an internship.
