Overview

Welcome to the web page of the database research group of the Department of Computer Science of the University of Maryland.

We are located in the A. V. Williams building of the College Park campus. The 6 faculty members of the group lead efforts in many different research areas through various projects and work closely with the Institute for Advanced Computer Studies and the Institute for Systems Research. Our group is considered one of the best in the country.

Faculty

Current Research

  • Exploring data management challenges in: life sciences databases, sensor networks, social networks, moving objects, P2P.
  • Data warehouses; OLAP.
  • Distributed data acquisition and data dissemination.
  • Spatial databases; visualization and indexing for high-dimensional data.
  • Developing statistical modeling techniques and integrating them with traditional database systems.
  • Management of probabilistic, imprecise and incomplete data.
  • Adaptive query processing; Data Streams.
