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.

Dr. Ashleigh Glover



Postdoc





Ashleigh earned her B.S. in biological sciences and M.S. in ecology and sustainability from California State University, Stanislaus. She earned her PhD in Fall 2024. Her thesis investigated spatial variation in reproductive barriers and genomic differentiation between a pair of hybridizing Neodiprion sister species. She is now a postdoc in the lab and has shifted her focus to the genetic mechanisms that produce host adaptation and reproductive isolation. 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 combines genomic approaches with morphometrics and ecological data to understand how and why insect ovipositors vary within and between insect species.

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.

Able Chow



PhD Student





Able earned his B.S. in Entomology from the University of Florida and his M.S. in Entomology from Louisiana State University. He joined the lab in Fall 2024. His Ph.D. research focuses on understanding the role of mitonuclear incompatibilities in speciation and describing how these incompatibilities shape patterns of gene flow in nature. When not in the lab, he enjoys tinkering with his computer and walking his cat.
