Currently I am a postdoctoral researcher at Technische Universität Berlin in the group of Financial and Actuarial Mathematics headed by Prof. Dr. Peter K. Friz . In particular, I am involved in the B04 project "Mean-field games, rough analysis and optimal trading" of the CRC/TRR 388 "Rough Analysis, Stochastic Dynamics and Related Fields " . Before that, I received my PhD from the National Techincal University of Athens (NTUA), under the supervision of Prof. Antonis Papapantoleon and I am a junior member of the Financial Engineering and Mathematical Optimization Lab . Also, I was a postgraduate student at Warwick University in the Master of Advanced Study (MASt) in Mathematical Sciences. Finally at first, I completed the Applied Mahematical Sciences (MSc) program and my undergraduate studies at the School of Applied Mathematical and Physical Sciences at NTUA.
