A selfie of me in a courtyard at Penn

Hi, I’m Jeff! I’m currently a second-year PhD student at the University of Pennsylvania where I’m advised by Professors Andrew Head and Ryan Marcus.

Previously, I was an MS Thesis student at Columbia University where I worked on systems to support data visualization interfaces, advised by Professor Eugene Wu.

In a past life, I worked as a senior full-stack software engineer at MongoDB and Microsoft.
