I am a postdoctoral researcher at the Section for Cognitive Section, DTU Compute. I have been working on learning the structure and dynamics of dynamic complex networks under the guidance of Prof. Sune Lehmann and Prof. Morten Mørup.

I obtained my Ph.D. degree under the supervision of Assist. Prof. Fragkiskos Malliaros and Prof. Nikos Paragios at CentraleSupelec, University of Paris-Saclay, where I was also a member of the Centre for Visual Computing and the Inria OPIS team. My doctoral research was oriented around developing representation learning methods for graph-structured data.

Before my Ph.D. studies, I received my Bachelor degree in Mathematics and my Master’s degree in Computer Engineering from Boğaziçi University. I worked with Prof. Ali Taylan Cemgil during my Master’s thesis studies on random graphs with prescribed degree distributions and their applications.
