I am currently a ZJU 100 Young Professor in the College of Computer Science and Technology at Zhejiang University. Before joining Zhejiang University, I served as an Associate (tenured) Professor in the School of Software Engineering at Sun Yat-sen University. I received my Ph.D. from the Faculty of Information Technology at Monash University. I am very fortunate to have been advised by many outstanding researchers during my studies, including Prof. John Grundy, Dr. Jiangshan Yu, Prof. Xin Xia, Prof. Xiapu Luo and Prof. Ting Chen.
