He has led research and launched significant product features in recommenders for the Google Play Store and Google+. Previous to Google, he was the Area Manager and a Principal Scientist at Palo Alto Research Center's Augmented Social Cognition Group, where he led the group in understanding how social computing systems help groups of people to remember, think and reason.
