My primary research interests include:

Previously I worked on dynamic analysis of Android applications. In the malware-lab of the FH Hagenberg Secure Informations Systems we started a project that provides a dynamic analysis platform for Android applications. This resulted in my first publication.

Later I also patched Taintdroid to contain taint sinks/sources/tags for cryptography APIs, which can result in insights how an application uses cryptography to protect user data.

I started a small project that does compile time function call instrumentation in LLVM. You could call it aspect oriented programming ;). It's focused on analysis though and does come with a significant overhead.

I did my master thesis at the IAIK Secure Systems groups, where I build upon the results of the Write Integrity Testing paper.
