Mehmet Aygün

I am a researcher in machine learning and computer vision, with a focus on generative and self-supervised models. My work aims to reduce supervision requirements and improve robustness in real-world settings. I received my Ph.D. from the University of Edinburgh, where I was advised by Oisin Mac Aodha. Before that, I worked with Laura Leal-Taixéat the Technical University of Munich on problems in scene understanding.

I am broadly interested in machine learning and computer vision. My work focuses on developing models that can learn fundamental priors and representations with minimal supervision, particularly through generative and self-supervised approaches. I am also interested in improving robustness and generalization in these systems.

This thesis advances computer vision by improving semantic correspondence, unsupervised 3D shape recovery, and self-supervised learning with 3D priors. Together, these methods enhance model robustness and move machine perception closer to human-level understanding..
