Bio:

I was graduated from School of Automation Science and Electrical Engineering, Beihang University in Sep. 2011 with Ph.D. From Jan. 2008 to Jan. 2009, supported by the China Scholarship Council (CSC), I visited School of Computer Science, Cardiff University, UK as a visiting scholar. Then, I worked as a Guest Researcher at the Information Technology Lab (ITL), National Institute of Standards and Technology (NIST), U.S. from Jul. 2009 to Jul. 2011. After that, I came back to China and worked as a postdoctoral researcher at ICST, Peking University, where I became an Assistant Professor in Jun. 2013 and was promoted to Associate Professor in Aug. 2015.

Research:                    Back to top

My research interests include Computer Graphics, Computer Vision, Pattern Recognition and Artificial Intelligence. More specifically, we have been working on the following topics in last few years. (1) Easy/automatic generation of large-scale Chinese font libraries. we proposed a series of solutions including radical assembling based and style learning based methods, making the easy/automatic generation of large-scale Chinese fonts become possible. (2) Calligraphic aesthetic assessment and font recognition. We proposed to adopt several machine learning approaches (e.g., artificial neural networks, sparse coding, etc.) to effectively evaluate the aesthetic visual quality of Chinese handwritings and recognize font styles. (3) Non-rigid 3D shape retrieval. We developed a number of canonical form construction methods to covert non-rigid 3D shape searching tasks into rigid cases, for which several view-based 3D shape matching approaches are proposed to effectively address the problems.

Achievements:                    Back to top

I have published more than 60 academic papers, including 1 ESI Highly Cited Paper (top 1%), 3 full paper in ACM Transactions on Graphics (TOG), 3 full papers in International Journal of Computer Vision (IJCV, a top-tier journal in Computer Vision), and several top conference (e.g., CVPR, IJCAI, SIGGRAPH Asia, AAAI, MM) papers. I was the principle investigator of two projects funded by National Natural Science Foundation of China and a project supported by the special funding of China Postdoctoral Foundation, and has led our group to successfully develop two 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. Our works on 3D shape analysis and retrieval have been cited more than 1400 times (until April 2020) by papers published in prestigious journals and conference including IJCV, TPAMI, TOG, CVPR, etc.
