About
I am a PhD student at the Technical University of Munich, supervised by Prof. Pramod Bhatotia at the Systems Research Group. I am interested in systems research with a particular focus on confidential computing, operating systems, and emerging hardware architectures. The central theme of my current work is to employ a hardware-software co-design approach to ensure high performance, security, and reliability.
Currently, I am interning at Intel Labs advised by Dmitrii Kuvaiskii and Mona Vij, where I am exploring confidential computing support for hardware accelerators in disaggregated architectures.
