I am a postdoctoral researcher at the University of Toronto working with Sven Dickinson.
Before joining UofT I spent five years as a PhD student and research engineer at CentraleSupélec, where I was advised by Iasonas Kokkinos.
My alma mater is the National Technical University of Athens.

Research Interests

I am interested in exploring the use of mid-level elements, such as medial axes and object parts, to improve detection, segmentation and fine-grain recognition of objects. In my latest projects, I have also worked on developing deep learning systems for semantic segmentation in natural and medical images.
