About me
I am in my fifth year of my PhD at the MIT Operations Research Center, where I am very fortunate to be advised by Prof. David Gamarnik. My primary research interests are in probability theory, high dimensional statistics and theory of machine learning. From June 2017 to August 2017 I was an intern at the Microsoft Research Lab in New Enland, mentored by Jennifer Chayes and Christian Borgs . Prior joining MIT, I completed a Master of Advanced Studies in Mathematics (Part III of the Mathematical Tripos) at the University of Cambridge and a BA in Mathematics from the Mathematics Department at the University of Athens.
