Sašo Grozdanov is an associate professor of physics at the Faculty of Mathematics and Physics, University of Ljubljana, and a faculty member and Ernest Rutherford Fellow at the Higgs Centre for Theoretical Physics, University of Edinburgh. He received his bachelor’s degree from Harvard University, his master’s from Cambridge University and his doctorate from Oxford University. He has a broad interest in uncovering the laws that govern physics using theoretical and mathematical methods that span from low to high energies: from hydrodynamics to quantum field theory, gravity and black holes, and string theory. A strong focus of his work has been on studying the dynamics of hot collective states that behave as fluids and plasmas. An example of such a state is the quark-gluon plasma that filled the early universe and can now be created in particle accelerators.
