Stefanovska's research concerns biological oscillations, particularly in the blood circulatory system, and their analysis using wavelets, nonlinear systems, and the Kuramoto model for systems of coupled oscillators.[2][3] With Peter V. E. McClintock, she is co-editor of the book Physics of Biological Oscillators: New Insights into Non-Equilibrium and Non-Autonomous Systems (Springer, 2021).
Stefanovska earned a master's degree in electrical and computer engineering at the University of Ljubljana in 1988,[5] and completed her PhD there in 1992 with the dissertation Self-organisation of Biological Systems Influenced By Electric Currents, under the joint supervision of Lojze Vodovnik [sl] and Hermann Haken.[6] As a student, she worked with Haken at the University of Stuttgart in Germany.[7]
She headed the group of nonlinear dynamics and synergetics as a faculty member at the University of Ljubljana, before moving to Lancaster,[5] where she has been a professor since 2010.[8]
