Bio

I'm an Assistant Professor at the Department of Cognitive Science and Artificial Intelligence at Tilburg University. I was previously a Postdoctoral Researcher at Robotics Institute , Carnegie Mellon University working with Jeffrey Cohn, a Postdoctoral Researcher at Affect Analysis Group, University of Pittsburgh and a visiting Ph.D. student at Pattern Recognition and Bioinformatics Group, Delft University of Technology. I received my B.Sc., M.Sc. and Ph.D. degrees from Computer Engineering Department at Middle East Technical University, where my supervisor was Fatos Yarman Vural.
