I am a computer scientist specialized in natural language processing and information retrieval, currently working as a Research Fellow at RMIT University with Mark Sanderson and Falk Scholer. My recent work has focused on summarization, representation, unsupervised learning, and information-theoretic methods.
I received my doctorate in 2013 from National Taiwan University. Prior to that, I worked with a number of people, including my advisor Jieh Hsiang at National Taiwan University, Andrew Gordon at ICT/USC, and Lee-Feng Chien at Academia Sinica. I received my B.S. and M.S. respectively from National Taiwan University in 2001 and 2003.

I am father of two boys. Also a classic rock fan, a bassist, and a Linux user. Like beers and math. (Who wouldn't?)
