Research interests

My interests are broad and every evolving. Disease ecology and evolutionary genetics are a passion that spider webs into many other fields of interest. Computer science and coding are wrapped up in with these interests. My ultimate goal is to help conserve nature and wildlife by helping humanity understand it.



Growing up in both Illinois and Wyoming I would spend my time looking for animals and learning about the many amphibian and reptile species that lived in these different environments. I found my love for research while attending the University of Wyoming. During my undergraduate years I was fortunate to be involved in research and publications. My first research experience was with Dr. Bowman and helping his lab in learning the functions of proteins involved in chromosome segregation in Agrobacterium tumafaciens. My second research experience was with Dr. Sondgeroth in her lab. There I worked on helping identify a distinct strain of Mycoplasma bovis that was associated with fatal pneumonia in Pronghorn. After graduation, I secured a position as Assistant Research Scientist and Lab Manager at the Ernest Wildlife Genomics and Disease Ecology Lab.  I conducted lab work and assisted with research to identify geospatial relationships among PRNP gene variation associated with differences in Chronic Wasting Disease time of onset and severity.

In addition to my research I have developed a passion for computer science and coding. I have been very fortunate to meet amazing people and work for incredible professors here at University of Wyoming.
