Achievements:                    Back to top

I have published more than 100 academic papers in prestigious journals and conferences (e.g., ToG, TPAMI, IJCV, SIGGRAPH/SIGGRAPH Asia, CVPR, NeurIPS, ICCV, etc). I was the principal investigator of several projects funded by the National Natural Science Foundation of China, Beijing Nova Program of Science and Technology, etc., and have led our group to successfully develop practical systems for the generation of Chinese fonts. These systems and techniques related to computer fonts have been adopted by a company called Founder Handwriting since 2016 to create font products that have served millions of users, making significant social and economic benefits.
