I completed my PhD at University of Thessaly, Greece, under the supervision of Iordanis Koutsopoulos. I then worked as a Post-doctoral researcher with Leandros Tassiulas for 4 years at CERTH and Yale University, where I was also co-supervised by Nicholas Christakis. I continued as an Assist. Prof with Trinity College Dublin for 4 exciting years, where I collaborated with Douglas J. Leith until 2020. During 5/2021-5/2024 I was splitting my time between TU Delft and Amazon (Visiting Academic), working with the team of G. Paschos.
