Johann Gaebler is a Ph.D. student at Stanford's Institute for Computational and Mathematical Engineering (ICME) working in the Stanford Computational Policy Lab (SCPL). Johann is broadly interested in the development and application of data science tools to complex social problems, such as mass incarceration, hiring discrimination, and other issues at the intersection of statistics, computer science, and policy. Previously, Johann worked at the ACLU and received an M.Sc. in the History of Science from Oxford University, and an A.B. in mathematics from Harvard University. In his free time, Johann likes to backpack, play the guitar, and learn new languages.
