Louiqa Raschid received a Bachelor of Technology in electrical engineering from the Indian Institute of Technology, Madras, in 1980, and a Ph.D. in electrical engineering from the University of Florida, Gainesville, in 1987. She is a Professor in the Smith School of Business and holds a joint appointment with the Institute for Advanced Computer Studies and the Department of Computer Science at the University of Maryland in College Park.

Dr. Raschid's research interests include scalable architectures for computation with heterogeneous servers, e.g., biomolecular data sources; tuning of data delivery to clients in fixed and mobile networks; and publishing and locating sources based on quality and content metadata using the WWW and XML. Her research has been published in high quality conferences (ACM SIGMOD, VLDB, IEEE ICDE and ICDCS, EDBT) and journals (ACM TODS, IEEE TKDE, IEEE ToC, the Journal of Logic Programming, the VLDB Journal and the Journal of Parallel and Distributed Computing).

Papers that she has co-authored have been nominated for Best Paper at the 1996 International Conference on Distributed Computing Systems and the 1998 International Conference on Cooperative Information Systems. Her research is supported by grants from the National Science Foundation and the Defense Advanced Research Projects Agency. She was an organizer of a Workshop on Data Management for Cellular and Molecular Biology sponsored by the NSF and the National Institutes of Health in 2003. She was an invited speaker at the 1999 Russian National Conference on Digital Libraries. She was recognized by the Vice President of Research at the University of Maryland to be among the Top 100 Faculty in obtaining external research funding.

Dr. Raschid serves on the editorial board of ACM Computing Surveys, the IEEE Transactions on Knowledge and Data Engineering, the Journal of Very Large Data Bases, and the INFORMS Journal of Computing. She is a member of IEEE, ACM, and the Society of Women Engineers.
