Supraja Sridhara

I am a PhD student at the Secure and Trustworthy Computing group at ETH Zurich. I focus on making the digital world a secure and trusted space. I have been working on extending the trust boundaries of trusted execution environments to different devices (like GPUs) in cloud deployments. This will enable power computation on the cloud without compromising the security or privacy of its data or applications.

During my PhD, I interned at Intel Labs in the summer of 2024, where I worked on confidential computing and trusted IO. Before starting my PhD, I graduated with a Master’s degree in Computer Science from ETH Zürich. Prior to that, I worked as a software engineer at Cisco, where I gained valuable experience in the field of software development and engineering.
