 His research has led to shipping new features in Bing, Viva, PowerBI.  He also shipped new tools to combat tech fraud.  Many of the supporting libraries have been open sourced in collaboration on GitHub (E.g. graphrag (opens in new tab), graspologic, (opens in new tab)showwhy (opens in new tab)).  Prior to joining Microsoft, Jonathan was Chief Scientist and Technical Fellow at Sotera Defense Solutions on assignment to DARPA, and led a variety of research across several programs.  Jonathan has also led large-scale data science efforts at Google, Zillow, and the US Army.  Early in his career, he also worked several startups and incubators.
