Biography

I am an Associate Professor at Tianjin University. Previously, I was a Postdoctoral researcher at the University of Tokyo, working with Prof. Lei Ma. I received my Ph.D. degree from the University of Luxembourg, advised by Prof. Yves Le Traon. Before that, I received my Master degree from Kyushu University, advised by Prof. Jianjun Zhao.

My research interests span the areas of software engineering and deep learning, including SE4AI and AI4SE.
Our recent survey about label-efficient testing of DL can be found at Survey.
