My current research is focused on two areas: (1) modelling the estrogen (menstrual) cycle in humans to study cycle abnormalities, and (2) the use of
stocking, harvesting and migration to control the dynamical behavior of deterministic models in population biology and genetics.

Title: Some Deterministic Models in Mathematical Biology and Their Simulations
Instructors: James F. Selgrade (North Carolina State University),
Cammey Cole (Meredith College)
and Huseyin Kocak (University of Miami)
This course presented and
analyzed the Hodgkin-Huxley and FitzHugh-Nagumo models, chemostat
models, pharmacokinetics models and discrete population models. The class was conducted in
a computer lab where participants used the software Phaser to simulate model behavior.

A similar MAA minicourse was held at Meredith College, March 2005.
