I am an Associate Professor at the Department of Computer Science at the Pontificia Universidad Catolica de Chile, and the director of the Center for Semantic Web Research. I received a Ph.D. from the University of Toronto in 2005. My research interests are in different aspects of databases, such as expressive power of query languages, database semantics, inconsistency handling, database design, XML databases, data exchange, metadata management and database aspects of the Semantic Web. I have received an IBM Ph.D. Fellowship (2004), eight best paper awards (PODS 2003, PODS 2005, ISWC 2006, ICDT 2010, ESWC 2011, PODS 2011, WWW 2012 and ISWC 2014) and an ACM-SIGMOD Dissertation Award Honorable Mention in 2006 for my Ph.D. dissertation "Design Principles for XML Data". I have served on multiple program committees and editorial boards, and I participated as an invited expert in the World Wide Web Consortium group that standardized a language for translating relational data into RDF. According to Google Scholar, my articles have received 5030 citations, and my h-index is 34.
