Teaching Interests: I am interested in teaching both theoretical and applied classes, ranging from calculus through graduate level. Involving students in undergraduate as well as graduate research and thesis direction is another aspect of education that is important to me.
Research Interests: To date, my research has focused on developing new deterministic and stochastic epidemic models for the spread of disease in structured host populations. Past models have included differences as well as differential equations with either fixed or periodic coefficients. Current epidemic models include amphibian movement between ponds and competition/predation amongst different species. I use theory as well as simulations to investigate the richness of the models.
Ongoing interdepartmental collaborative work includes studying dairy mastitis and forecasting modeling of downy mildew on onions.
Future directions in research include investigating the robustness of stability results, animal movement models, patch models studying the spread and control of influenza, and population genetics. Parallel algorithms and genetic algorithms will most likely be of great use in exploring these new topics.

I graduated from Tarleton State University in May 2009 with a Bachelor’s degree in Mathematics and a certification to teach 7–12 grade math. After graduation, I began working toward my master’s degree in mathematics, but life had other plans and pulled me away for a while. I spent the next 12 years teaching at two different high schools, where I gained invaluable experience and a deeper love for education. I then returned to Tarleton as an academic advisor—and it was during that time that I felt called to finish what I started. In December 2022, I proudly completed my Master’s in Mathematics! I am currently seeking my PhD in experimental psychology
