Recent work

• Seven months at Mozilla doing applied ML and networking research on Firefox’s privacy team. Built models to defend hundreds of millions of users from the trackers and fingerprinting scripts that quietly run on almost every page of the open web.
• Built Firefox’s new tab widget surfacing metrics for enhanced tracking protection. Closed a handful of security bugs along the way.

Sillier facts
