Short Bio

I am an Associate Professor at the department of Information Engineering, the Chinese University of Hong Kong (CUHK) since 2018, after having worked here for six years as Assistant Professor. I received my PhD degree from Indiana University at Bloominton in 2012.

Previously, I have received my B.S. and M.E. degree in 2001 and 2004 on computer science and computer engineering respectively. From 2004 to 2006, I was working as an FPGA (Field Programmable Gated Array) logic design engineer at Harbour Networks (now acquired by Huawei) at Beijing.

For prospective students

I am still looking for new talented PhD students who are interersted in network and system security. Please send me your CV first (with email address shown on the left).
