The Faculty of Physics at the University of Belgrade has around 73 professors and assistants working across 3 buildings. It has around 1000 students enrolled in its bachelor's, master's and PhD programs each year. The faculty focuses on basic and applied research in fields like nanoscience, materials science, condensed matter physics, lasers, plasma and meteorology. It has research centers in nanoscience and synthesis of nanostructures that collaborate internationally on projects.
