Welcome!

I am a Ph.D. candidate in Computer Science at Stony Brook University, New York, advised by Prof. Dimitris Samaras. My research interests are in the fields of computer vision and deep learning, with a special focus on 3D-aware models for human motion synthesis and human face reconstruction, as well as audio-driven generative networks. During my PhD, I have also conducted research as a Research Scientist Intern at Meta Reality Labs. Previously, I was a Machine Learning Engineer at Behavioral Signals, working on speech emotion recognition. I received my Diploma in Electrical and Computer Engineering at National Technical University of Athens in Greece, where I did my thesis under the guidance of Prof. Alexandros Potamianos.
