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.
I will be joining NYU's Center for Data Science (CDS) as a CDSMooreSloan Fellow in September 2019!
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 England, 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.
