Professor Uses Language of Math to Describe Natural Phenomena
Professor Uses Language of Math to Describe Natural Phenomena At first glance, populations of wild animals might seem to have nothing in common with laser-based communications devices, and rivers to have little to do with macroeconomic theory.But they all can be modeled using methods of dynamical systems theory. “In my field of work, I try to mathematically describe dynamical systems and processes,” said Dr. Dmitry Rachinskiy, a professor of mathematical sciences who recently joined the UT Dallas faculty. By applying principles of mathematics to such systems, which change over time, Rachinskiy said scientists and engineers can better understand problems and phenomena in biology, physics, chemistry, technology, geosciences and economics, among other fields. “This research is applicable to many different areas, for example, population dynamics, where you have a community of several species forming an ecological system,” Rachinskiy explained. “The number of animals changes over time, and you may want to predict what those changes will be and how to control them. Dynamical systems theory gives you a means to formulate a mathematical model that will help predict how different factors affect population numbers.”
