I am a Ph.D. candidate in Computer Science at Brown University and advised by Tim Kraska. I am part of Brown's Data Management group and MIT's Learned Systems group and specializing in systems research and ML-for-Systems.

In my Ph.D., I research the use of Machine Learning techniques to engineer LearnedSort, a new, learning-enhanced, sorting algorithm. So far, our work has achieved outstanding performance in comparison to state-of-the-art approaches.

Before my time at Brown, I received my bachelor's degree from Bilkent University in Turkey. During that time I undertook a few side projects and volunteered for the Erasmus Student Network and Crossing Paths.
