Research Interests
Dr. Rugonyi's main research interests include the analysis of biological systems, and the development of mathematical and numerical models that describe them. Many advances in the medical field require a thorough understanding of complex physico-chemical interactions. Finite element methods and other numerical techniques, when used with appropriate physically-based models, provide a means of calculating and visualizing the response of systems to different conditions, and could therefore become essential to guide the development of treatments for diseases. Dr. Rugonyi's current research is focused on two areas: i) the study of monomolecular layers at the air-water interface that are used to understand the physical basis for the behavior of pulmonary surfactant in the lungs; and ii) the study of cardiovascular systems, which includes the analysis of blood flow through vessels and the heart, as well as the interaction of flow with tissue.
