About me

(c) Frank

I am a postdoc working in geometric analysis and mapping theory in singular spaces. I was born in Athens, grew up in Finland, and received my PhD from the University of Helsinki under the supervision of Ilkka Holopainen in 2016.

I currently work with Stefan Wenger at the University of Fribourg, Switzerland, using tools from analysis on metric spaces and geometric measure theory to study  Plateau-type problems and minimal surfaces in metric spaces admitting a quadratic isoperimetric inequality.
