About

I am a Ph.D. student in Computer Science at the University of California, Riverside, advised by Prof. Nael Abu-Ghazaleh. Before UCR, I received my B.Sc. in Electrical and Electronics Engineering from Middle East Technical University (METU) in Ankara, Turkey.

My research is on the security of GPUs and memory systems. I look for ways that hardware features such as page migration, Rowhammer mitigations and multi-GPU interconnects can be used to break isolation, and I design defenses against these attacks. My work has appeared at IEEE S&P, USENIX Security and ACM CCS.

I am looking for opportunities in offensive/defensive hardware security research.
