“It might seem unfair to reward a person for having so much pleasure over the years, asking the maize plant to solve specific problems and then watching its responses.”— Barbara McClintock

I feel I have been a biologist all my life. Having been born and raised in Oak Ridge, Tennessee, home of Oak Ridge National Laboratories, science was all around me. My father worked in the Plutonium Lab at the Y-12 Plant, and that is essentially all that I ever knew about his work. While my father always hoped I would study chemistry, I gravitated toward biology. Growing up in the 1960s was great as I was allowed to wander from home to spend my summer days exploring the forested ridges surrounding my home with my binoculars and bird guide. In many ways, I feel like I never grew up as I continue to explore and study the biological world much the way I did as a child.
From birds, my interest moved to snakes while working toward my bachelor’s and master’s degrees at the University of Tennessee in Knoxville. It was there that I developed a strong interest in venomous snakes–specifically the phylogenetic relationships between pit vipers and true vipers. Just before commencing with my master’s degree, I took a break from formal learning and spent two years working in Germany where I learned to speak and read German. It was a great experience for me, and it made it possible for me to spend two years at the University of Bonn while working on my Ph.D. at the Museum Koenig in Bonn. I would later earn my Ph.D. from the University of Michigan where I wrote my dissertation on morphological differences among the viperid snakes.
I feel blessed that my life’s experiences led me to a career teaching biology at Hillsdale College. Being free from having to apply for government grants has allowed me to pursue research directions of my own interests. While at Hillsdale College, I have led students to conduct research on conservation genetics in South Africa and Botswana. Hillsdale College students worked hand-in-hand with game rangers and conservationists in Africa to gather data that benefits management of the genetic health of a range of animals including African lions, cheetah, elephants, Cape buffalo, and southern ground hornbills.
