From April 2023, I am a Professor of Computer Science at Ruhr University Bochum (RUB). Before joining RUB, I was an Associate Professor at the School of Computer and Mathematical Sciences at the University of Adelaide. I earned my Ph.D. in Computer Science from the University of Adelaide in 2014, and my M.Sc. in Computer Science and B.Sc. in Mathematics and Computer Science from the Hebrew University of Jerusalem in 1993 and 1990, respectively. In between I have been the Vice President of Research in Memco Software and a co-founder and Chief Technology Officer of Girafa.com.

My research explores the security of the interface between the software and the hardware. In particular, I am interested in the discrepancy between the way that programmers think about software execution and the concrete execution in modern processors. I work on identifying micro-architectural vulnerabilities, and on exploitation and mitigation techniques.
