Biography

I am a tenure-track associate professor in the school of computer science and engineering at Southeast University, starting from fall 2021. Before that, I was a postdoctoral researcher in CT research group in Department of Medical Physics at University of Wisconsin-Madison advised by Dr. Guang-Hong Chen and Dr. Ke Li. My research projects are related to x-ray imaging systems and algorithms. I served as an reviewer for journals including IEEE Transactions on Medical Imaging and Medical Physics. For more detailed information related to me, you can download a copy of my CV.
