Personnel

Michael (Michi) Tobler

Michi graduated with a Ph. D. from the University of Zürich. He is interested in a wide range of questions in evolutionary biology. His current work leverages livebearing fishes as a model to ask questions about the origins of functional trait diversity and speciation. He strives to make science – and biology in particular – accessible to broad audiences.

Graduate students


Nick Barts

Ph.D. student, Graduate Assistance in Areas of National Need (GAANN) Fellow

Nick received his Bachelor’s degree in Integrative Biology from the University of Illinois in 2015. He is interested in comparative physiology and assessing how traits across levels of biological organization interact to shape organismal responses to stressful environments. His current research focuses on the comparative physiology and biochemistry of locally adapted populations of Poecilia mexicana that inhabit hydrogen sulfide-rich springs, with an emphasis on metabolic and detoxification pathways.

John Coffin

Ph.D. student, Graduate Assistance in Areas of National Need (GAANN) Fellow

John received a dual Bachelor’s degree in Ecology and Marine Biology from the University of Georgia in 2017. His interests include investigating fish ecology and larval development. In particular, he hopes to understand how organisms can adapt to novel environments using a variety of physiological and computational tools. His current Ph.D. research examines the mechanisms and evolution of heavy metal tolerance in Western mosquitofish (Gambusia affinis) populations living in freshwater streams contaminated with mine outflow.

Libby Wilson

Ph.D. student

Libby received a B.S. in Biology and a B.A. in Spanish from Truman State University in 2018. She is broadly interested in mechanisms underlying biodiversity and speciation. Libby’s current research focus involves identifying the microbiomes of fish in sulfidic habitats and understanding how host-microbiome relationships potentially influence ecological function and physiological adaptation to extreme environments.
