M.S. Middle East Technical University, Turkey
Ph.D. Florida Institute of Technology 1992
Professional ExperienceDr. KÃ¶ksalÂ’s areas of expertise are stability analysis of nonlinear ordinary differential equations, neural networks and mathematical modeling.
Current ResearchDr. Koksal is currently working on several projects that involve both undergraduate and graduate students:
1. Neural Networks: Construction and analysis of Fuzzy backpropagation neural networks with vector valued activation functions, and application to data fusion.
2. Biochemical Networks: Mathematical modeling of protein activities during oocyte maturation and fertilization. Nonlinear ordinary differential equations and neural networks approach are used for modeling.
3. Coral Dynamics: Modeling coral population thresholds and vital rates using nonlinear difference and differential equations.
