• After 3 and a half years of working as software developer for Cazoodle Inc., I have moved to New York City to pursue a PhD in Computer Science (August 2012)

I am a Ph.D. candidate in Computer Science at NYU Polytechnic School of Engineering, under supervision of Prof. Juliana Freire. Before, I was working as software developer for Cazoodle Inc., where I participated in multiple projects, from visual crawling and scheduling to web developments. I used to work as a freelance developer in my free time before coming to the US. I got my BE in Computer Science from School of Information and Communication Technology (SoICT) at Hanoi University of Science and Technology (HUST) in Vietnam.

My research interests are mainly in the area of data management: large-scale data analysis, data integration, social network and urban data analysis.

My current projects:

• Spatio-Temporal Textual Index: Develop an efficient spatio-temporal textual index that handles spatial, temporal and textual components uniformly, archives high efficiency both in space usage and query evaluation.
• Twitter as Social Sensor for News: Associating topics from traditional news sources and social media messages in order to use tweets as social sensor for news.
• Who Owns New York City: Joint work with NYU Furman Center for Real Estate and Urban Policy. We have been developing entity matching algorithms to integrate various state and local administrative datasets to identify people behind corporate owners of rental housings and the full extent of their portfolios.
