Letizia Tanca studied Mathematics at the University of Naples, where she obtained her Master's degree in Mathematical Logic; she then worked for four years as a software engineer in telecommunication firms. Letizia Tanca obtained her Ph.D. in Computer Science in 1988. Later, she remained with Politecnico di Milano first as a research associate and then as an associate professor, until 1994, when she became a full professor at the University of Bari. She joined the University of Verona in 1995 and stayed there as the dean of the Computer Science course until 1998. Letizia Tanca is currently with Politecnico di Milano again, as a full professor. In all these universities she has taught and teaches courses on Databases and the Foundations of Computer Science. She is the author of several papers on databases and database theory, published in international journals and conferences, and of the book "Logic Programming and Databases", coauthored with S. Ceri and G. Gottlob. She has taken part to several national and international projects. Her research interests range over all database theory, especially on deductive, active and object oriented databases, graph-based languages for databases, and the semantics of advanced database and information systems. Her current research interests concern the representation and querying of semistructured information, particularly information on the World Wide Web. An evolution of this research has recently caused an interest for text mark-up languages, especially XML, and the study of "soft" query and constraint spefification methods based on fuzzy techniques. Letizia Tanca has been a referee of several international journals, and a member of the programm committee of a large number of international conferences. She has co-edited, together with Dan Suciu, a special issue of the Journal of Computer Systems Science and Engineering on Semantics in the World Wide Web.
