Data Scientist - Core Data Science

I am a Data Scientist specializing in basic social science and macro-level product analysis across the Meta family of apps. I have been at Meta since January 2007, when I joined as the company’s first dedicated Data Scientist. In that role, I supported the company’s user growth and product growth during its early years. As an Engineering Manager during 2012 – 2018, I helped to build and support teams for developing company-wide analytics capabilities: company metrics, experimentation tools, survey tools, logging infrastructure, and data discovery. Prior to Meta, I studied Symbolic Systems and Economics at Stanford University.
