My interests lie at the interface of mathematics and biology, specifically mathematical modeling of population dynamics in the fields of ecology and epidemiology. My primary specialization is in model selection, where one tries to answer the question of which mathematical model best represents a system or best explains a set of data. By selecting the most parsimonious model (the model that best balances simplicity with goodness of fit), we can answer important questions about the populations under study. Typical questions one can answer with these methods are, “How long will it take for this population to go extinct under the current conditions?” or “How many people do we need to vaccinate to eradicate this disease?”

I’m always interested in working with students to study biological systems using mathematical models!

**Modeling the Impact of the Invasive Evil Weevil on the Endangered Giant Air Plant Population of Florida:**We wish to study the endangered giant air plant of Florida (T. utriculata) and its invasive predator, the evil weevil (M. callizona). The air plant in Florida is semelparous, which means it has one, large sexual reproduction event in its lifetime by growing an apical meristem. The weevil consumes this meristem before the plant is able to reproduce, causing it to head towards extinction. We are building and analyzing an agent-based model of this system to determine effective control strategies as well as evolutionary impacts on the plant species.

**Modeling Pollen Competition:**Many aspects of plant sex remain a mystery to the biological community. In this project, we will use mathematical and computer simulation models to study the dynamics of pollen competition and to determine successful evolutionary strategies. In particular, we will use an agent-based modeling (ABM) approach. ABMs are models where individuals (agents) are unique and autonomous and interact with each other and their environment locally. ABMs have become a popular modeling process in the last decade due to the rise of computational power so we will be able to answer novel biological problems with new modeling techniques!

**Modeling the Evolution of Language:**Language evolution differs significantly from genetic evolution because individuals’ use of language can change during their lifetime. This difference means that many of the techniques that are used for modeling genetic evolution, such as tracking generations, must be modified.
