I am an Associate Professor in the Information and Computer Sciences Department at the University of Hawaii at Manoa. Prior to my current appointment, I was a Research Staff Member at the IBM Thomas J Watson Research Center between 2004 and 2009. I received my Ph.D. in Computer Science from Duke University in 2004 and my M.Sc., B.Sc. in Computer Science from the National University of Singapore in 1999 and 1998 respectively.

I am also honored to serve as an IT consultant on several World Bank projects in China, Mongolia, Malaysia, and Vietnam.

My Curriculum Vitae is available here: pdf.


My research interests lie in the data management area and includes database query optimization, statistics and selectivity estimation, XML databases, stream processing, data warehousing, ontologies and semantic queries, etc. While at IBM, I had the pleasure of doing advanced development for DB2 9 pureXML, DB2 Index Compression and Infosphere streams, as well as filing over 25 patent applications.

More recently I am focusing on data analytics for renewable energy applications and am also investigating the use of blockchain in the government sector.

In my free time (which is not much these days with 2 small kids), I enjoy hiking and chinese martial arts. In particular, I used to practice and teach chen style taijiquan (aka Tai Chi), but my focus now is on I-Liq Chuan (意力拳) ( for classes in Honolulu, HI see I-Liq Chuan (Hawaii). I also teach and promote I-Liq Chuan as part of the activities of the Internal Martial Arts Club at UHM Registered Independent Organization (RIO) at the University of Hawai`i at Manoa.
