elisabethagoritsasElisabeth Agoritsas
Working with Francesco Zamponi, November 2016 – 2018
From 2018, independent postdoc at EPFL, Lausanne

Elisabeth Agoritsas has been a postdoctoral fellow at the LPT in the Ecole Normale Supérieure of Paris, working with Francesco Zamponi. She obtained her PhD in 2013 at the University of Geneva in Switzerland, under the supervision of Thierry Giamarchi. Then she moved to the LIPhy at the University Grenoble Alpes in France, for a three-year postdoc in the team of Jean-Louis Barrat. Half of this first postdoc was funded by an Early.Postdoc fellowship from the Swiss National Science Foundation (Nov. 2014 – April 2016). Since November 2016 she has started a new postdoc with Francesco Zamponi, directly funded by the Simons collaboration.

Her research interests are gathered in the statistical physics of disordered systems, mostly classical and using analytical approaches. During her PhD she studied the theoretical framework of disordered elastic systems and the modelling of one-dimensional interfaces, a problem which is related to the broad Kardar-Parisi-Zhang universality class. Since her postdoc in Grenoble she is in addition studying plasticity in structurally disordered systems, such as yield stress fluids or amorphous solids, using mesoscopic elasto-plastic models which can be used to describe, at coarse-grained scale, their non-linear response and underlying dynamics under shear.
