Data and Information Systems

The rapid growth of big data creates unprecedented demand and opportunities for developing powerful intelligent data and information systems that help people organize, search, analyze, and manage data, information and knowledge.

Our faculty work on a wide range of research problems, tackling the many challenges associated with developing such intelligent systems and their applications. Research includes structuring and organizing massive data and information, helping people search and find relevant data and information; mining actionable knowledge from massive, heterogeneous typed data; optimizing the entire workflow of data access, analytics, and exploration; analyzing large social/information networks, optimizing human-computer collaboration centered on data, and exploring broad data-intensive applications.

Our faculty work closely with industry, and many of our algorithms are used in a wide range of information system applications, especially in database and data analytics systems, data mining systems, search engines, and web information service systems.

Strengths and Impact

DAIS faculty have created an active, dynamic and collaborative research environment, leading a large group of graduate students, pioneering research in the frontiers of database systems, data mining, information retrieval, Web information systems, as well as their social and scientific applications, and generating impactful results.

Many graduates are professors in major U.S. or international universities (e.g., Georgia Tech, Univ. of Michigan, UCLA, UCSD, UCSB, USC, Penn State, Purdue, Notre Dame, Univ of Virginia, Vanderbilt) and industry research labs (e.g., Google Research, IBM Research, Microsoft Research, Adobe Research), and major industry (e.g., Google, Facebook, Microsoft) and received prominent awards (e.g., NSF Career awards, KDD/SIGMOD Dissertation Awards, KDD innovation awards).

The research results generated by the DAIS groups have been highly cited and some results have been popularly used in industry and academia and collected in textbooks. DAIS faculty have been highly active in the corresponding international research communities, winning many research paper awards, major research awards, and student awards, invited to deliver keynote conference speeches and conference tutorials, and claim competition awards on multiple occasions.


  • The DAIS Seminar features invited researchers, DAIS faculty and graduate students. Seminars will be announced on the DAIS mailing list (as are other items of interest to the DAIS community). It is quick and easy to subscribe to the DAIS mailing list.
  • Illinois Computer Science Speaker Series: brings prominent leaders and experts to campus to share their ideas and promote conversations about important challenges and topics in the discipline.
