I am a research fellow working with Prof. Paulo Esteves-Verissimo at CritiX , SnT , University of Luxembourg . I am also an honorary research fellow working with Prof. Mark Ryan in the School of Computer Science, University of Birmingham, UK, where I received my PhD in computer science.

My research interests are in the area of cyber security and cryptography. In particular, the focus of my research has been on design and analysis of cryptographic protocols, cryptographic key management, and ledger-based (a.k.a. blockchain) applications.

Main research impact:
My work on ledger-based end-to-end secure messaging system has attracted news media's attention and has been covered by more than 30 international and national news media including Science Daily, Phys.org, ACM TechNews, EurekAlert, Futurism, and Silicon Republic. The news has been released in more than 7 languages by media from more than 10 countries including UK, US, Germany, Ireland, Luxembourg, Turkey, Spain, and India. I have also been invited for an interview (to explain my innovation to general listeners) by Eldoradio --- a member of RTL group which is one of the world's leading producers of television content and the leading European entertainment network.

My patent-pending ledger-based applications have been further developed by a University of Birmingham spin-off, and have attracted funding support from Innovate UK.

I've co-designed a secure booting solution for Huawei Ltd, the largest telecommunications equipment manufacturer in the world, to manage their next generation network devices securely.

    icon Martial Arts

    I'm a big fan of martial arts since I was a kid, and I was really into Wuxia novels and Kung Fu movies (mainly acted by Bruce Lee, Jet Li, Jacky Chen, Jing Wu, and Donnie Yen). I finally started to learn Kung Fu in 1999 with my first Sifu. Later, I started to learn Jeet Kune Do around 2002, Tai chi in 2003, Sanshou in 2005, Tian Gang Mian Zhang in 2006, The Five Elements of Xing Yi Quan in 2007, Muay Thai in 2007, Fanzi quan, Chin Na (joint lock techniques) and Mongolian wrestling in 2009. I became a Kung Fu coach and an assistant Sanshou coach in 2008, and I got a part time job for teaching stand up technique in a Mixed martial arts (MMA) school in Australia in 2010, and founded Endless Martial Arts Association in 2011. I've been invited several times to give performance in different places (e.g. Viva La Gong at Wollongong, AU; Town Hall at Birmingham, UK; etc).
