Research Interests
I have eclectic interests in ecology and environmental biology, including population modeling, environmental toxicology, conservation, and the use of genetic approaches to answer ecological questions in aquatic ecosystems.

In the Eggert Lab, I am working to pinpoint the taxonomic status of the Neosho smallmouth bass (Micropterus dolomieu velox), one of two currently recognized smallmouth subspecies along with the Northern variety (M. dolomieu dolomieu). Specifically, I am using both mitochondrial and microsatellite DNA markers to measure genetic differentiation among geographically isolated smallmouth bass populations. By evaluating the genetic relatedness of populations from different ecoregions, it may be possible to determine whether the Neosho smallmouth bass constitutes its own unique species of conservation concern. I hope to use this assessment to inform decisions related to stocking programs and wildlife management.

In May 2015, I graduated from William Jewell with dual B.A. degrees in Biology and Mathematics and a minor in Spanish. I spent most of my freshman year studying the effects of visual and olfactory predatory cues associated with the scorpion Centruroides vittatus on the foraging behavior of wolf-spiders (Rabidosa punctulata). The following year, I collaborated with two other students to evaluate the effect of the protein kinase C inhibitor PMA (phorbol myristate acetate) on proliferation and differentiation in K562 leukemia stem cells. During my junior and senior years at William Jewell, I worked to construct a mathematical model of a reciprocal intraguild predation system as an independent thesis project. I used Lotka-Volterra models associated with competition and predator-prey interactions to build a system of population growth equations for a top predator (Centruroides vitattus), an intermediate predator (Rabidosa punctulata), and a basal resource species.
