Biography: 

Louiqa Raschid is a professor in the Smith School of Business.

Her research has made significant contributions toward solving the challenges of data management, data integration, and performance for applications in the life sciences, internet data delivery, health information, financial information systems, humanitarian IT applications, and Grid computing.

Raschid's research spans the fields of computer science to business information systems to life science data management, and she is an expert in optimization and large-scale simulation; modeling, semantics and logic-based reasoning; and data management and analysis techniques. She has published more than 140 papers in leading conferences and journals in databases, scientific computing, internet data management, bioinformatics and artificial intelligence, including the ACM SIGMOD, VLDB, AAAI, IEEE ICDE, ACM TODS, IEEE TKDE, IEEE ToC, and the Journal of Logic Programming.

Raschid's research has received multiple awards, including more than 25 grants from the National Science Foundation (NSF) and DARPA. She was named an ACM Distinguished Scientist in 2008.

She has organized working groups on information mediation and biological data management for the National Institutes of Health and DARPA. Raschid is leading an effort sponsored by the NSF and the Office of Financial Research (under the Department of the Treasury) on the next generation financial cyberinfrastructure.

She has advised and mentored more than 30 doctoral or post-doctoral researchers, including many women and minority students, and has more than 100 co-authors or co-editors.

Raschid has played a key role in the Sahana FOSS project for disaster information management, including serving as database architect, member of the Sahana Software Foundation, and founding chair of the Sahana Board (2007 to 2009). Sahana is the only comprehensive product for disaster information management. Sahana is an outgrowth of the 2004 tsunami in Sri Lanka.

She received her doctorate in electrical engineering from the University of Florida.
