Daniel Hernández

I am currently a postdoctoral researcher in the Analytic Computing department of the Institute for Parallel and Distributed Systems at the University of Stuttgart. Previously, I was a postdoctoral researcher in the Computer Science Department at Aalborg University and worked at Millennium Institute Foundational Research on Data in Chile. I hold a Ph.D. in Computer Science from the DCC, University of Chile. I'm interested in Open Data, databases, and the Web. You can contact me by email (daniel@degu.cl).
