Chuck Lam is currently founding a mobile social networking startup called RollCall. It’s building the social secretary for active individuals.
Previously Chuck was a Senior Tech Lead at RockYou. There he developed social applications and data processing infrastructure handling hundreds of millions of users. He applied A/B testing and statistical analysis to tune the virality of social apps. He also optimized RockYou’s ad network with the use of real-time and social data. He was able to improve response rates dramatically, sometimes by an order of magnitude.
Chuck first got interested in big data when he began his PhD study at Stanford. He learned of the significant effect big data has on machine learning and began to explore its consequences. His thesis, “Computational Data Acquisition” was the first to investigate creative approaches to data acquisition for machine learning, adopting ideas from areas such as open source software and online games.
