Sara Comai is associate professor at the Dipartimento di Elettronica e Informazione of Politecnico di Milano since March 2007. She received her Ph.D. in Ingegneria Informatica e Automatica from Politecnico di Milano on January 13, 2000. Her recent research interests include the specification, design and automatic generation of complex Web applications. In particular, she contributed to the language WebML, a visual notation for the conceptual specification of large Web applications. Her focus was mainly on the analysis of the composition and navigations models of such language with the aim of identifying useful properties for the specification of correct hypertexts. The study of WebML and of its semantics have given a contribute to the book "Designing Data-Intensive Web Applications" published by Morgan Kaufmann in December 2002, co-authored by Sara Comai. The book has been translated in Italy in 2003 by McGraw-Hill with the title "Progettazione di dati e applicazioni per il Web". She studied also several extensions of WebML for the design of advanced Web applications integrated with workflow and Web services. Part of this research has been done within the European IST WebSI project, funded by the European Union, where Sara Comai was the technical responsible. Currently, she is working on the extensions of the methodologies for the specification of Web applications towards Rich Internet Applications (RIA). She published several papers in journals and international and national conferences in the fields of Web and databases. She organized some workshops and tracks in international conferences and was member of several program committees of international conferences and workshops. Currently, she teaches Algorithms and Data Structures and Advanced Data Bases. She taught also Computer Graphics and courses on Programming.
