Dr. Christoph
Kerschbaumer
Christoph Kerschbaumer picture I am passionate about building an open, independent, secure and privacy respecting web for all of us!

I have over a decade of experience in Secure Systems Development and currently am managing the Firefox Security & Privacy Engineering team at Mozilla.

My work ranges from designing secure systems with fail safe defaults to fighting cross site scripting as well as preventing man-in-the-middle attacks.

I received my PhD in Computer Science from the University of California, Irvine where I based my research on information flow tracking techniques within web browsers.

Prior to being a graduate research scholar, I received a M.Sc. and B.Sc. in Computer Science from the Technical University Graz, Austria.
