I’m currently employed as Application Catalyst at Metaweb tasked to help enabling a development ecosystem around Freebase as a platform.

Previously, I was a research scientist at MIT working on the SIMILE Project for the Digital Library Research Group of the MIT Libraries.

I am also known for my open source activities within the Apache Software Foundation (ASF) of which I’ve been a member since 1999 and a director between 2003 and 2005. There, I’m mostly known for having started the Apache Cocoon project and, before that, for having being a release manager for Apache JServ (a servlet container now retired, precursor of Apache Tomcat). But you can find some of my code lying around several open source projects.

I has also participated in several expert groups within the Java Community Process, such as the Servlet API, the Java XML API and more recently the Java Content Repository API.

My current research interests include data integration, data mining and data visualization, virtual communities dynamics, software usability, user interface design and software engineering.
