Nisa Bostanci
PhD Student @ ETH Zurich
I am currently a PhD student in SAFARI Research Group at ETH Zurich led by Prof. Onur Mutlu. I am broadly interested in computer architecture and particularly in memory systems, focusing on their robustness and performance. Recently, I have been working on low cost and scalable read disturbance mitigation techniques to improve the robustness of DRAM-based computing systems, and exploring the robustness of emerging computing paradigms and future systems, such as processing-in-memory, against vulnerabilities.
Before starting my PhD, I was a member of the Kasirga Microprocessors' Lab in TOBB ETU. I led and contributed to many exciting projects, including various RISC-V-based processor and microcontroller designs.
