Qianru Sun 孙倩茹

I am an Assistant Professor (tenure track) in the School of Information Systems, Singapore Management University, since Aug 2019. From Apr 2018 to Jul 2019, I was a Joint Research Fellow working with Prof. Tat-Seng Chua at the National University of Singapore and Prof.Dr. Bernt Schiele at the MPI for Informatics. From Mar 2016 to Mar 2018, I held the Lise Meitner Award Fellowship and worked with Prof.Dr. Bernt Schiele and Dr. Mario Fritz at the MPI for Informatics. In Jan 2016, I obtained my Ph.D. degree from Peking University and my thesis was advised by Prof. Hong Liu. From Oct 2014 to Jan 2015, I was a visiting Ph.D. student advised by Prof. Tatsuya Harada at the University of Tokyo. My research interests are computer vision and machine learning that aim to develop efficient algorithms and systems for visual understanding.
