Eleni Pachyli

I am currently a second year PhD student at TU Wien in the group of Prof. Ivan Izmestiev.

I am interested in discrete geometry, discrete L²–Hodge theory and differential geometry.

I completed my master's degree at the University of Leipzig, and my bachelor's degree at the National and Kapodistrian University of Athens. During that, I did an exchange at Eberhard Karls University of Tübingen.
