Piotr Kapuściński received a doctorate in physics in 2021 after participating in a joint doctoral program between Université Grenoble Alpes in France and Wrocław University of Science and Technology in Poland. His doctoral research focused on the excitonic properties of atomically thin transition metal dichalcogenides. Following this, he completed a 12-month postdoctoral fellowship at the Laboratoire National des Champs Magnétiques Intenses in Grenoble, France, where he continued studying transition metal dichalcogenides and expanded his research to layered magnets from the transition metal phosphorus trichalcogenides family. Since 2023, he has been affiliated with the Faculty of Physics at the University of Warsaw. His current research involves the optical spectroscopy of birefringent liquid crystal microcavities and the study of exciton-polaritons and spin-orbit coupling of light in such systems.
