Zhuojia Shen

Software Engineer at Apple

Hello there!

I am Zhuojia Shen (沈卓佳), a Software Engineer at Apple. I obtained my PhD from the Department of Computer Science at the University of Rochester, where I was advised by Prof. John Criswell. Before that, I got my Bachelor’s degree in School of Computer Science at Beijing Institute of Technology.

Research Interests

I work on the broad area of computer systems security. My current research interests lie in low-cost security enforcement on ARM systems, using novel combinations of hardware and architectural features as well as operating system and compiler techniques. I also had experience developing novel software-based defenses against side-channel attacks.
