About This Group

How google web server handle trillions of clicks from all around the world? How GPS give drivers routes based on shortest distance/shortest time? How facebook suggest friends based on your profile? The answers to these questions involve data management to a great extent.

Our group focuses on research in query processing on both streaming and relational database systems, management and indexing of large databases, spatio-temporal database applications, security issues in data management field, query processing in probabilistic data, and distributed DBMS. We strive for innovative algorithm design in the context of above research areas.
