This kind of work is often referred to as mathematical modeling. Mathematical modelers, like Kondic, formulate mathematical equations that are believed to describe physical, biological, or sociological phenomena. The modelers take the known and accepted formulas of physics and/or chemistry and create mathematical equations that described unexplained phenomenon--such as why two fluids may adhere. While mathematical modeling may not always validate a fundamental physical or chemical principle, if the answer matches most of the presumed data, then researchers know they may be on the right path. Scientists in many fields, including biology, chemistry, physics, and engineering use mathematical modeling in their research. Economists, sociologists, and political scientists also utilize sophisticated mathematical modeling to deal with detailed problems associated with human behavior.
Kondic is the author of more than 50 research articles. His most recent scholarly article, "On Nontrivial Traveling Waves in Thin Film Flows, Including Contact Lines" appeared in September of 2005 in Physica D. The National Science Foundation, NASA and the International Exchange of Scholars have supported Kondic's work. Kondic received his doctorate in physics from City College of City University of New York.
