Dr. Catherine Linnen



Principal Investigator





Catherine (she/her) earned her B.S. in Ecology from the University of Georgia. She then went on to complete her Ph.D. in Brian Farrell's lab and a postdoc in Hopi Hoekstra's lab, both in the Department of Organismic and Evolutionary Biology at Harvard University. She is currently an Associate Professor in the Department of Biology at the University of Kentucky. When not in the lab, she enjoys spending time with her family.

Dr. Alaine Hippee



Postdoc





Alaine (she/her) received her B.S in Biology from the University of Iowa. She then entered the Integrated Biology (iBio) Program at the University of Iowa as a Master’s student under the guidance of Dr. Andrew Forbes. Following the completion of her M.S, she remained in the Forbes lab, earning her PhD studying the evolutionary history of specialist fruit flies (genus Strauzia). As a postdoc in the Linnen Lab, Alaine is investigating the relationship between changes in gene expression and adaptation to novel plant hosts in Neodiprion.

Serena Limberg



Lab manager





Serena is originally from New Hampshire and came to UK to study biology. She graduated in the spring of 2023 with a degree in biology and a minor in math! In her spare time she can be found at the barn with her horse.

Ashleigh Glover



PhD Candidate





Ashleigh earned her B.S. in biological sciences and M.S. in ecology and sustainability from California State University, Stanislaus. For her PhD dissertation, she is investigating spatial variation in reproductive barriers and genomic differentiation between a pair of hybridizing Neodiprion sister species. The overarching goal of her dissertation is to infer causal links between reproductive isolation traits and genomic differentiation to gain a greater understanding of speciation. Outside of the lab, Ashleigh enjoys scuba diving and spending time with her family.

Ryan Ridenbaugh



PhD Candidate





Ryan (he/him) am an evolutionary biologist and systematist who graduated from the University of Central Florida with both his B.S. and M.S. in Biological Sciences. He broadly focuses on the biodiversity of the insect order Hymenoptera, and the underlying mechanisms driving speciation in this group. His Ph.D. research focuses on mechanosensitive ion channels in the sawfly ovipositor, and how these channels impact host choice and fitness.

Jakeb Watts



PhD Student





Jakeb earned his B.S. in Biology from Hanover College and his M.S. in Biological Sciences from Eastern Illinois University. His research interests include biodiversity, behavior, and the processes driving speciation. His current research focuses on understanding the effects of hybridization of Neodiprion sister species in mating and reproductive outcomes in males.
