About me

Hello! My name is Dimitri and I am a 2nd year PhD student in Computer Science at JHU, working with Professor Nicolas Loizou. I am broadly interested in the fields of Optimization and Machine Learning.

Prior to joining JHU, I graduated with a BSc in Mathematics from the National and Kapodistrian University of Athens (NKUA) and a MSc in Data Science and Machine Learning from National Technical University of Athens (NTUA). Moreover I have a MSc in Mathematics from Germany.

CV available upon request.
