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 Hank Levy, Arvind Krishnamurthy, 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.
