Dr. Das is the Associate Dean for Research, College of Engineering, a Distinguished University Chair Professor
of Computer
Science and Engineering, Director
of the Center for
Artificial Intelligence and Big Data (CARIDA), and Director of the Database
Exploration Laboratory (DBXLAB) at UT-Arlington.
Prior to joining UTA in 2004, he has held positions at Microsoft Research, Compaq
Corporation and the University of
Memphis. He graduated with a B.Tech in computer science from IIT Kanpur, India in 1983, and with a Ph.D
in computer science from the University of
Wisconsin, Madison in 1990. He is a Fellow of the IEEE and a Fellow of
the ACM.
His early research interests were in
computational geometry and graph theory. His Ph.D dissertation made several
significant contributions to important problems in these areas, including
the discovery of greedy graph spanners,
the discovery of exclusion regions for minimum weight triangulations, and
determining the complexity of convex polyhedral separability. In the
subsequent decades, his research interests broadened to all aspects of Big
Data Exploration, including data management, data analytics, machine
learning and data mining. Some highlights of his contributions have been on
keyword search and ranking in databases (e.g., the early DBXplorer system), time series
mining, approximate query processing, and Deep Web analytics. He is
presently working on areas such as machine learning approaches for
approximate query processing, and fairness and explainability in data
management systems.
Dr. Das has published over 200 papers, many
of which have appeared in premier data mining, database and algorithms
conferences and journals. His work has received several awards, including
the Communications of the ACM Research Highlights in 2021, ACM SIGMOD
Research Highlights in 2019, IEEE ICDE 10-Year Influential Paper Award in
2012, ACM SIGKDD Doctoral Dissertation Award (honorable mention) in 2014
for his former student, and numerous other awards. He has presented
keynotes and invited lectures, tutorials and courses at various
universities, research labs, and conferences. He has been on the Editorial
Board of the journals ACM
Transactions on Database Systems and IEEE Transactions on Knowledge and Data Engineering. He has
served in the organization roles of several major conferences, including as
General Chair of ACM SIGMOD/PODS 2018.
His research has been supported by grants
from National Science Foundation, Army Research Office, Office of Naval
Research, Department of Education, Texas Higher Education Coordinating
Board, Qatar Foundation, AT&T, Microsoft Research, Nokia Research, Cadence
Design Systems and Apollo Data Technologies.
