First things first: my name is John, but I go by Jack.
I am currently employed as a Research Scientist at Zap Energy on the Theory and Modeling team. Prior to that, I completed my PhD in Applied Mathematics at the University of Washington. I was co-advised by Professors Uri Shumlak of the Aeronautics and Astronautics department, and Jingwei Hu of the Applied Mathematics department.
Prior to graduate school, I worked at Square on the Payments Engineering team, and was a technical co-founder at Inscriptive, Inc.
