Biography: 

Ashok Agrawala joined the Department of Computer Science at the University of Maryland in 1971. He also holds joint positions with UMIACS and the Department of Electrical Engineering.

For the past 30 years, he has pursued research activities in the design, implementation and performance of computer systems. He is recognized for achievements in the areas of transient analysis of queues, distributed algorithms, and hard real-time systems design. Much of his research has gained national and corporate recognition through practical applications of his innovative solutions in these areas worldwide.

He is the author of seven books and more than 200 technical papers. Agrawala has also served as a consultant to the UNDP, the government of India, and as a technical expert for legal casework. His research activities have been supported by various federal agencies including DARPA, NSF and AFOSR. Corporate support has been received from IBM, Novell, AT&T and others. His former students includes more than 30 Ph.D. graduates who serve on the faculty of prestigious universities, as well as in nationally recognized industrial research labs and successful high-tech companies, operating both nationally and abroad. Before joining the faculty of the computer science department, Agrawala worked at Honeywell Information Systems, where he successfully designed an Optical Character Reader.

Agrawala received his B.E. and M.E. degrees in electrical engineering from the Indian Institute of Sciences, as well as master's and doctorate degrees in applied mathematics from Harvard University. He is also a Fellow of the IEEE and a member of the ACM, AAAS, and Sigma Xi.
