About Me

I am Professor for IT Security at University of Lübeck.  I received my Ph.D. in ECE from Ruhr University Bochum, Germany, where I worked as a member of the Horst Goertz Institute for IT Security (HGI). From 2010 I  spent two years at the Center for Cryptology and Information Security (CCIS) at Florida Atlantic University. In 2012 I joined the Electrical and Computer Engineering Department at WPI. Since August of 2017, I am the Director of the Institute for IT Security at the University of Lübeck.

My research interests are in:

  • Applied Cryptology
  • Systems security and secure computer architecture
  • Side channel analysis, physical attacks and their prevention
  • Cloud and virtualization security
