Professor Yorke's current research projects range from chaos theory and weather prediction and genome research to the population dynamics of the HIV/AIDS epidemic.
He is perhaps best known to the general public for coining the mathematical term "chaos" with T.Y. Li in a 1975 paper entitled "Period Three Implies Chaos". "Chaos" is a mathematical concept in non-linear dynamics for systems that vary according to precise deterministic laws but appear to behave in random fashion. The University's chaos research group, one of the best in the world. The objective of his chaos research is to describe those robust properties that are common in the dynamics of physical, biological, and chemical systems. Sometimes the phenomena can be described using rigorous mathematics, and sometimes only phenomenological descriptions can be obtained from intensive numerical studies. Most often, the research is a blend of numerical and rigorous techniques.
