Content Security Tech Lead

I am the Content Security Tech Lead at Mozilla with over a decade of experience in Secure Systems Development. My work ranges from designing 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.
