Research
My research focuses on building systems that are both reliable and secure. In particular, during the last years, I have developed techniques and methodologies that are particularly suited to address this problem in the context of core software systems – the building blocks in modern computing that other software layers critically rely upon, such as operating systems, hypervisors and distributed systems.
I tackle this problem from three directions:- Gathering insights about the impact of emerging trends on reliability and security, by conducting real-world, empirical studies
- Building systematic testing tools that scale to modern, complex systems
- Designing and redesigning systems for reliability and security
I was postdoc at the University of Washington where I worked with Arvind Krishnamurthy, Hank Levy, and Xi Wang. Before that, I graduated from MPI-SWS and the University of Saarland where I worked with Rodrigo Rodrigues. Not long ago, I also had the chance to closely collaborate with Andrew Baumann, Pramod Bhatotia, Björn Brandenburg, Joao Carreira, Cheng Li, and Kaiyuan Zhang.
I am looking for talented, highly motivated PhD students to work in my lab!
Prospective students should explain their research interests and how they relate to my work in their application.
