I am aiming to build up a trusted mobile environment for activities related to mobile devices and establish trust intelligence for pervasive and ubiquitous services and computing.

I participated in a number of research projects related to mobile commerce, services and applications, trusted computing and communications, and software platform at NRC. My research focuses on the issues related to trust and security.

Current Research

• Reputation systems
• Trust in human computer interaction 
• Autonomic trust management
• User driven trust modeling and management, usable trust management
• Trust4All: a trustworthy middleware platform for component software
• Trusted computing platform

Current Project

• Human-machine trust interaction
• AwareNet
• Future Internet

Education

I have received my doctoral degree and Licentiate degree from the Helsinki University of Technology (TKK). I have two M.Eng got from the Xi'an Jiaotong University in 1997 and the National University of Singapore in 2000, respectively.

Others

My biggest achievement in my life so far is having my son in 2004. My current hobbies are playing badminton and yoga, from which I made friends and improve my health. I am seeking their skill improvement -- another technical issue.
