Hello! I'm Carlos and welcome to my Web page

This is my academic/work/professional home page so here you will find some of my publications and my current research interests. Currently I'm a postdoctoral researcher at the Database Research Group at Pontificia Universidad Católica de Chile. Before I did my PhD at the Ontology Engineerig Group, at Universidad Politécnica de Madrid. I won the Best Computer Science PhD thesis for the work you can find here.

My research interest is accessing RDF data around the Web. Thus, I do research in distributed query processing, focusing on distributing SPARQL queries to the Web of Data and improving the access to it.  

Current Projects

Currently I work in my own postdoctoral project funded by the Chilean Research Commission. I also work as researcher in the Millennium Nucleus Center for Semantic Web Research, supported by the Chilean Goverment.

SPARQL Endpoint Status (SPARQLES): Tracks the health of public SPARQL endpoints.

SPARQL 1.1 Federated Query: Editor of the W3C Recommendarion.

SPARQL-DQP: Distributed SPARQL query processor using data workflows.
