PC Member of WoMO 2006, 2007, The International Workshop on Ontologies: Reasoning and Modularity (WORM-08), WoMo 2011, 2012 and Co-chair of WoMo 2010

Worked on various topics related to semantic web, including semantic wikis, closed world reasoning with OWL, provenance, policy languages, and linked data.

At BBN, I worked on an ontology model for composite networks including communication networks, social networks and information networks. I'm also involved in developing a "semantic information theory" which extends the classical information theory with semantics.

Work on policy and rule language modeling, including AIR, XACML and RIF. Also worked on XBRL financial data modeling

Engaged in the design of the OWL 2 language. Co-authored two W3C Recommendations: "rdf:PlainLiteral: A Datatype for RDF Plain Literals" and "OWL 2 Web Ontology Language Quick Reference Guide"

Work on modular ontologies and privacy-preserving inference

In the Department of Computer Science and the Center for Computational Intelligence, Learning, & Discovery

Worked on Machine Learning, Pattern Recognition and Image Processing at the Image and Information Processing Lab
