University of Tennessee, Knoxville (US)
Prof. Suzanne Lenhart is a Chancellor's Professor in the Mathematics Department at the University of Tennessee, Knoxville (US), Associate Director for Education and Outreach at the National Institute for Mathematical and Biological Synthesis (US), and was Part-time Researcher at the Oak Ridge National Laboratory (US) for 22 years. She is a recognized expert in optimal control and partial differential equations, with modeling applications to populations, natural resources, and diseases. She has authored more than 200 journal articles, as well as two texts, Optimal Control applied to Biological Models and Mathematics for the Life Sciences. She was elected as a fellow of the American Association for the Advancement of Science, SIAM, and the American Mathematical Society. In 2017, she was selected as a fellow of the Association for Women in Mathematics, an association in which she was President between 2001 and 2003.
Optimal control for management of aquatic population models
Optimal control techniques of ordinary and partial differential equations will be introduced to consider management strategies for two different aquatic populations. In the first example, managing invasive species in rivers can be assisted by adjustment of flow rates. Control of a flow rate in a partial differential equation model for a population in a river will be used to keep the population from moving upstream. The second example represents a food chain on the Turkish coast of the Black Sea. Using data from the anchovy landings in Turkey, optimal control of the harvesting rate of the anchovy population in a system of three ordinary differential equations (anchovy, jellyfish and zooplankton) will give management strategies.
