Currently work as CEO of Zet Universe, Inc. Previously worked for Microsoft, Google, and Microsoft Research, in different roles varying from developer relations to program management and HCI research.

I'm interested in information retrieval (data mining, ontologies, taxonomies & folksonomies, semantic search), information semantics representation (concept spaces, semantic web, semantic storage), graphs (from social & interest graphs towards meaning graph), information visualization, contextually-aware computing and human-computer interaction.
