"Mathematics reveals its secretes only to those who approach it with pure love, for its own beauty"
― Archimedes 

I am currently a Visiting Assistant Professor at the Dioscuri Centre for Topological Data Analysis (TDA) at the Institute of Mathematics of the Polish Academy of Sciences. I am working in the area of topological data analysis (TDA) which is a new approach to the analysis of datasets using techniques from algebraic topology. I am interested in the mathematical foundations of TDA, and their connections to dynamical systems and mathematical biology You can contact me at astefanou (at) impan (dot) pl
