BIOGRAPHY

I am the Content Security Tech Lead at Mozilla with over 10 years 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.
