Yohan Beugin

Welcome! I am a Ph.D. student in the Department of Computer Sciences at the University of Wisconsin–Madison where I am a member of the Security and Privacy Research Group and advised by Prof. Patrick McDaniel.

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.
