I recently joined Tsinghua University as an Assistant Professor, after spending three wonderful years at Cornell University, where I was fortunate to work with Prof. Kilian Weinberger. I received my Ph.D. degree from Tsinghua University in 2015. My research focuses on machine learning and computer vision, in particular deep learning, resource-efficient learning and unsupervised learning. Our work on DenseNet won the Best Paper Award of CVPR (2017). (C.V.)
