Network design (telecommunications and logistics), data mining, auctions, network and combinatorial optimization techniques.
Dr. Raghavan's research interests and activities cover a broad domain including--- auction design, data mining, economics, information systems, computational marketing, networks, optimization, and telecommunications. He has published on a wide variety of topics (including telecommunications, electronic markets, and data mining) and numerous academic outlets such as Management Science, Operations Research, Decision Support Systems, and the INFORMS Journal on Computing. He holds two patents, and has won numerous awards for his research work. He is most proud of his Ph.D. students (8 graduated and 2 current) who have done outstanding research, and won several major awards for their doctoral dissertation work.
The unifying feature to Dr. Raghavan's research is the network and combinatorial optimization techniques he applies to these problems. Raghavan's research is supported by the National Science Foundation and the National Security Agency. Recently, he has finished co-editing a book on Telecommunications Network Design and Management. He has received several patents and prestigious awards for his research, including the George B.Dantzig Dissertation Award from INFORMS. Prior to joining the University of Maryland he led the Optimization Group at US WEST Advanced Technologies.
