James Edgar Keesling, PhD, Professor in the Department of Mathematics at the University of Florida, has been recognized by Marquis Who’s Who Top Educators for dedication, achievements, and leadership in mathematics and education.

Interested in mathematics from an early age, Dr. Keesling loves sharing the knowledge he has accrued with the younger generations. He has been a professor in the Department of Mathematics at the University of Florida since 1976, having previously served as an assistant professor, associate professor, chair of the Department of Mathematics, and Colonel Allen R. and Margaret G. Crow Term Professor. During this time, Dr. Keesling also lent his services to the University of Georgia and the University of Utah as a visiting professor, and to Australian National University as a fellow.

In addition to his work in academia, Dr. Keesling has been heavily involved with research. His interests lie in topology, dynamical systems, biomathematics, stochastic processes, numerical analysis, operations research, and applied mathematics. Throughout his career, he has published his findings in articles such as “A generalized definition of topological entropy,” “Relative risk in the multistage model of carcinogenesis,” and “Cancer incidence and the biology of extreme old age,” and developed a patient simulation code for the University of Florida Research Foundation. He has contributed to more than 100 publications, as well as a variety of conference presentations and invited addresses. He continues to aid his peers as the editor of “Revista Matemática Complutense, an advisory board member of “Topology and Its Applications,” and a visiting lecturer for the Society of Industrial and Applied Mathematics.

Dr. Keesling prepared for his career by earning a Bachelor of Science in industrial engineering from the University of Miami in 1964, a Master of Science in mathematics in 1966, and a PhD in mathematics in 1968. He is a member of the American Mathematical Society, the Mathematical Association of America, the Society for Industrial and Applied Mathematics, and the American Association for the Advancement of Science, as well as the Society for Mathematical Biology, The New York Academy of Sciences, Phi Kappa Phi, and Tau Beta Pi.

In recognition of his achievements, Dr. Keesling was named a Co-PD USDS-NIFA grantee by Iowa State University and the University of Florida, a CO-PI USDA-NIFA grantee by the University of California Davis and the University of Florida, a PI grantee by the Citrus Research and Development Foundation, a Co-PI grantee by the National Science Foundation, and a fellow of Australian National University. He was also awarded grants by the Applied and Computational Mathematics Program at the Defense Advanced Research Projects Agency, and the Conference on Combinatorial Theory and Linear Programming, and earned a TIP Award for teaching from the University of Florida. He has been featured in numerous editions of Who’s Who in America, Who’s Who in Science and Engineering, Who’s Who in the South and Southwest, Who’s Who in the World, and Who’s Who in American Education.

When Dr. Keesling isn’t working, he is very active in his community. He is currently a clerk of session, elder, and member of the First Presbyterian Church, a member of the Christian Fraternity at the University of Florida, and a faculty advisor for The Navigators.
