Research Overview

My current research interest is broadly focused on mobile sensing, computer vision and security. I believe that the proliferation of mobile devices is changing our lifestyle. I would like to enrich our daily life by making the most out of mobile devices. Along with the benefits is the increasing risk of privacy leak. I therefore also work on solutions that could make mobile devices safer.

Me on the Web

I’m fan of functional programming languages. I’ve tried some of them: Common Lisp, Clojure, Racket, and finally, Haskell. I’m facinated by the seemingly infinite possiblity of the whole new functional programming world. Well, I’m still learning. But I hope I could say I'm a Haskeller. I’m also interested in other open source projects and I consider myself a die-hard Linux user.
