PhD Student

Hey! I am a PhD student at Saarland University working for the CISPA Helmholtz Center for Information Security under the supervision of Dr. Michael Schwarz and Prof. Christian Rossow. I like to explore the microarchitectural security of modern computer systems. A particular interest of mine lies in the security implications of up-and-coming web features such as WebAssembly.
