He conducts interdisciplinary research in computational social science, network science, and urban informatics through quantitative analysis of large-scale data. At Yahoo he worked with production teams from Flickr and Tumblr to build social recommender systems at scale.

He serves in the PCs of several conferences including WWW, WSDM, ICWSM, and CIKM. He organized several academic events: organizer of the SNOW workshop at WWW, workshop and tutorial chair for ICWSM in 2015-16, and general chair of SocInfo in 2014. He led the work of Yahoo in the European project "SocialSensor". He is a co-organizer of the scientific dissemination meetup "DataBeers" in London and one of the founding members of GoodCityLife.org, a global network of scientist with the goal of giving a good life to city dwellers.
