Center for Studies in Physics and Biology
Dr. Vucelja is a theoretical physicist interested in biology, soft-condensed matter, and computational physics. She has studied mixing and clustering of particles in flows, problems relevant for understanding the formation of rain droplets and planetesimals, the clustering of pollutants on water surfaces, and many industrial applications. She derived the compressibility of surface flows and described the aggregation-disorder transition of particles in flows. Using chaotic mixing, she substantially accelerated certain Monte Carlo algorithms, the main numerical tools for studying complex systems. Dr. Vucelja went on to study the emergence of clones in populations. Drawing analogies between glassy systems and population dynamics, she calculated the rate of coalescence, or the probability of two individuals belonging to the same clone. Dr. Vucelja works on inference problems in population genetics, host-pathogen coevolution, amorphous solids, and the development of efficient algorithms for studying glassy systems.
