Yohan Beugin

I have received my M.S. in Computer Science and Engineering from the Pennsylvania State University as well as my Diplôme d'Ingénieur (M.S. and B.S. in Engineering Sciences) from the French Engineering School École Centrale de Lyon.

I am interested in building more secure, privacy-preserving, and trustworthy systems. My current research focuses on security of open-source software as well as tracking and privacy in online advertising.
