I am currently a Technical Fellow at Microsoft, working on NLWeb. I joined Microsoft from OpenAI, where I was a Technical Advisor to the CEO.

Earlier, I spent almost two decades at Google (working on DataCommons and Schema.org), IBM Almaden, Netscape, Apple ATG and MCC. I have also started multiple companies including Epinions and Alpiri.

Over the years I have played a significant role in the development of several standards that have found widespread adoption on the web, including RDF, RSS and Schema.org.

My research interests include Artificial Intelligence, Knowledge Representation, Structured data on the Web, Trust networks and Web Monetization.
