Facebook Projects
I love the space of privacy/security/abuse prevention and I've been involved in many projects in the area while at Facebook. Some examples:
- User Data Deletion and Retention
- Data Access tooling, such as Download Your Information
- Data Portability tooling, such as the Data Transfer Project
- Link shimming
- Cookies, and their handling
- End to End Encryption in Messenger
- Text Clustering and Cluster Classification for Abuse Prevention
Academic Life
I got my PhD on web application security from Imperial College London in 2013. My PhD thesis was on taint tracking, a technique to secure applications by monitoring data propagation at runtime.
I come from Athens, Greece. I graduated from the Electical and Computer Engineering Department of the National Technical University of Athens.
