I was born in Athens in 1989. I received my Diploma Degree in Electrical Engineering and Computer Science from the National Technical University of Athens in October 2015.
Since November 2015 I am a PhD candidate in the IRAL lab under the supervision of Prof. Petros Maragos.

My research interests lie at the crossroads of computer vision and audio processing for affective computing, including building affective multimodal virtual avatars and automatic emotion recognition systems.
