I am an assistant professor in the Department of Computer Engineering at Gaziantep University, Gaziantep, Turkiye. Before joining Gaziantep University, I was a faculty member in the Department of Computer Engineering at Iskenderun Technical University from 2020 to 2023. I received my Ph.D. in 2019 and my M.Sc. in 2013 from the Department of Computer Engineering at Hacettepe University, where I was supervised by Aykut Erdem and Erkut Erdem. During my Ph.D., I was a visiting researcher at the Amsterdam Machine Learning Lab, University of Amsterdam, where I worked with Zeynep Akata between October 2018 and January 2019.

My research focuses on image and video processing, computer vision, and computer graphics, with a particular interest in deep learning and deep generative models. I am especially interested in problems such as camera localization, video stabilization, and object goal navigation. I am always open to research collaborations and to working on challenging problems that connect visual understanding with practical applications.
