About me

I am a pursuing my Ph.D. as a member of the Visual Recognition Group, Czech Technical University in Prague, under the supervision of Professor Ondrej Chum.

My research focuses on learning image representations for large-scale visual recognition tasks. I am mainly interested in settings where the visual data is either on the fine-grained or instance level, and comes from (possibly) multiple visual domains.

Previously, I obtained my Engineering Diploma (5 year degree) at the school of Electrical & Computer Engineering, National Technical University of Athens.
