I am currently a Ph.D. candidate in the Computer Science department at Cornell University. I work in the database group with Professor Johannes Gehrke. You can find my CV here.

My current research interests lie in data management, particularly in fault tolerance for data-driven applications in the cloud, currently focusing on Massively Multiplayer Online Games(MMOs) and large-scale simulations.

I was born and grew up in Hanoi, the capital of Vietnam.


Data-driven applications in the cloud have fault-tolerance as one of their basic requirements. We are designing new state fault-tolerance techniques that are more adequate to the particularities of these applications. Interactive applications, such as MMOs, have latency as a major concern; on the other hand, non-interactive applications, such as scientific simulations, must be run on large clusters with low overhead. The experimental evaluations of our ongoing work showed that our new algorithms achieved nearly constant latency and more than one order-of-magnitude lower overhead than the best previous methods. Detailed descriptions can be found at our project page.

Prior to joining the database group, I worked with Professor Paul Francis on the Virtual Aggregation project to tackle the Internet-routing scalability problem. Virtual Aggregation is a configuration-only approach to shrinking the routing table on routers. It does not require any changes to router software or routing protocols and can be deployed independently and autonomously by any ISP. Evaluations show that Virtual Aggregation can reduce routing-table size on individual routers by one order of magnitude while imposing almost no traffic stretch and very little increase in router load.
