Julia Wiktor

Associate Professor at Condensed Matter and Materials Theory

Julia Wiktor joined Chalmers in May 2019. She obtained a M.Sc. degree from Grenoble INP in France and Gdansk Technical University in Poland. She carried out her PhD studies on nuclear materials at CEA Cadarache in France and was awarded a PhD degree by Aix-Marseille University in 2015. After graduating, she moved to EPFL in Switzerland for a postdoctoral stay focusing on solar materials.

Her main scientific interests are novel photoabsorbing materials for solar devices. In particular, she uses advanced electronic structure methods to study how complex physical phenomena occuring at the atomic scale affect the efficiency of solar devices.
