Saber Ganjisaffar

PhD Candidate

Hey there! I'm Saber Ganjisaffar, a Ph.D. Candidate in CSE at the University of California, Riverside (UCR). My research is focused on building secure and efficient computing systems, with a particular focus on hardware-software co-design for security. I delve into computer architecture and microarchitecture, using tools like architectural simulators to explore innovative approaches, identify optimization opportunities, and bring my research ideas to life. I'm also passionate about contributing to open-source simulator projects and collaborating on research that advances the state-of-the-art in system security and efficiency. My work has been published in conferences like ISCA, and I'm fortunate to be advised by Professor Nael Abu-Ghazaleh and Professor Chengyu Song.

I'm always open to new collaborations and interesting research opportunities. Feel free to reach out if you'd like to discuss potential projects or just chat about research!
