Research

My research is in the area of time scales. The calculus of time scales was developed to unify and extend results obtained for differential equations and difference equations. Currently, my focus is on oscillation criteria for certain linear and nonlinear second order dynamic equations. I am also interested in applications of time scales to mathematical biology and issues that affect pre-service teachers ability to teach mathematics.
