About me

I’m currently a PhD student at the Australian National University, supervised by Prof. Xiaoyu Sun. Previously, I got my Master’s degree from the School of Computer Science and Technology at Zhejiang University, advised by Prof. Chao Ni. Before that, I received my Bachelor’s degree from UESTC. My research interest includes Software Engineering and Software Security.
