I am currently a Fellow at Google, working on DataCommons, Schema.org and other projects. Earlier, I spent time at 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 Knowledge Representation, Structured data on the Web, Trust networks and Web Monetization.
