I was born in Athens in 1986. I received my Diploma in Applied Mathematics at the School of Applied Mathematical and Physical Science in National Technical University of Athens. My thesis was a numerical study of the performance of ecological composite materials. I obtained my Master degree in Computational Mechanics from the School of Chemical Engineering, NTUA.

I had been working for about a year in Cross-Media relations in multimodal discourse, in the COGNIMUSE project. I am currently a PhD student in the CVSP Group, under the supervision of Prof. Petros Maragos, working in the field of Computer Vision.
