Are you working in an organization that uses, is looking to use, and/or promotes Semantic Web and Linked Data?

Our group does research and development in ontology and semantic database management, including large RDF databases and large ontologies, both for the US Government and generally in the bio-informatics area.

What are your current skills and levels within the Semantic Web stack? i.e., XML, RDF, OWL, SPARQL, IA, etc.

My research is in mathematical and algorithmic methods for the analysis and interoperability of semantic databases, and especially semantic hierarchies. I routinely work with OWL, RDF, and SPARQL, and we are actively interested in SPARQL extensions.

What would you like to do and also learn within our organization?

It's critical for us to be at the forefront of current practice, and this organization within the Seattle community seems ideal. We are interesting in networking and communicating with all our local colleagues in the R+D community.

Will you help to lead discussions and workshops, and possibly organize?


Which areas would you like to provide assistance in? i.e., Discussions, Workshops, Organizing, etc.

I'd like to get to know the organization more before committing, but in principle we can be active participants in all activities.


I'm the Chief Scientist for Knowledge Sciences at the Pacific Northwest National Laboratory (PNNL). I'm in the Seattle office, while our headquarters is in Richland, Washington. I'm a mathematical systems theorist, computer scientist, and semiotician
