Tianhe Ren

I am currently a Ph.D. candidate at The University of Hong Kong, under the supervision of Prof. Xiaojuan Qi. Previously I was a senior computer vision engineer at The International Digital Economy Academy (IDEA), advised by Prof. Lei Zhang. In 2021, I got my bachelor's degree from MAC Lab in Xiamen University advised by Associate Prof. Yiyi Zhou and Prof. Rongrong Ji.

I'm primarily interested in researching vision foundation models, object detection and segmentation, and multi-modal learning. I'm also passionate about open-source projects in AI community. The research work and open-source projects I'm involved in have garnered more than 30.0K stars on Github.
