Ataberk Olgun is a Computer Architecture researcher and a Ph.D. student in SAFARI Research Group at ETH Z√ľrich led by Prof. Onur Mutlu. He obtained his BSc and MSc degrees from TOBB ET√ú under Prof. Ońüuz Ergin‚Äôs supervision.

His research interests lie primarily in the area of Computer Architecture. He is interested in designing reliable (and as performance and energy efficient) memory systems from the ground up. These days, he is trying to develop a better understanding of the RowHammer problem and come up with more efficient system-level solutions to it. Previously, he developed an FPGA-based DDR4 memory testing platform that enabled cutting-edge research characterizing real DDR3/4 and HBM2 DRAM chips. He built an end-to-end system design for processing-in-memory techniques using real off-the-shelf DDR3 chips, which he also prototyped on an FPGA-based system.

He worked at Kasirgalabs until 2021 where he led the design of a RISC-V system-on-chip that was later manufactured using SKY130 technology.

Even before then, he worked with Prof. Kemal Bicakci to develop an authentication method based on behavioral biometrics.
