I entered department of mathematics of Nankai University and studied pure mathematics in 1995. Then I was a graduate in department of information theory from college of mathematics in 1999, and my major research directions were complexity of sequences, information theory, and digital right management. During Mar. 2002-Sep. 2002, I took intern at the Internet Media group of Microsoft Research Asia; and during Dec. 2003-Aug. 2004, I stayed at the digital media group in IBM China Research Lab; my major research topics were digital right management schemes as well as digital watermarking there. Afterwards I obtained Ph. D. in Dec. 2004. Later I was in network group at college of information technical science as a postdoc. Then I stayed in Austrian Academy of Science(Osterreichische Academie der Wissenschaften) as an OEAD scholar in 2009, which was supported by a European research funding, and I visited Austrian Academy of Science several times from 2009 to 2020. I also obtained the Ernst Mach award in 2014. During 2015-2016 I am a visiting scholar at Department of Maths and Statistics of Carleton University, and Department of Electrical and Computer Engineering of University of Waterloo, Canada. I have taught courses including "Algorithm design and analysis ", "Network security"， "Security mechanisms in algorithms and protocols & Applications" , and "Mechanisms of Blockchains and related Applications" for undergraduates; as well as "Coding and information theory" for graduates. I am looking for self-motivated graduate students with good maths/is/cs background, who are interested in complexity measures & algorithms of sequences, and secure engineering related topoics. Please feel free to ask if you have more interest.
