Close up of servers

Our database group is known for its work in all aspects of data management in many scientific, commercial, and healthcare applications, such as:

  • Data modeling
  • Metadata management
  • Design of databases and applications
  • Integration of heterogeneous information
  • Data distribution
  • Data management performance

Our group’s most recent and active research includes projects in:

  • Data management in mobile and location-based services
  • Sensor and stream-based data management
  • Decision-support systems for patient treatment in clinical settings
  • Analysis of healthcare clinical and claim data
  • Modeling of bioinformatics and climate data
  • Privacy-preserving data mining
  • Outlier detection and analysis
  • Text mining of biomedical literature
  • Workflow and business process management
  • Database performance analysis in distributed, parallel, and cloud computing systems 
  • Internet data management, Web computing, and big data systems and analytics

Our group has a proud history; databases was the first Georgia Tech computing research area to be ranked by U.S. News & World Report in the early 1990s. We are particularly known for our database-centric research and expertise at the interfaces of systems, software engineering, machine learning, security, and GIS.

Our Ph.D. graduates have taken faculty positions at major universities, including Rice, Texas A&M, University of Texas-Dallas, LSU, and University of Illinois at Chicago, to name a few. Our alumni also populate research groups at Microsoft, LLNL, NCR, SAS, Rockwell Collins,, Orbitz, IBM Brazil, and others.

We enjoy close research relationships with IBM Almaden, IBM T.J. Watson Center, HP Labs, ATT and Wipro Technologies, and our major funders include NSF, NIH, CDC, IBM, Fujitsu Labs, Wipro Technologies, and Samsung.
