PI: Catherine Linnen

catherine.linnen@uky.edu, CV


Catherine earned her B.S. in Ecology from the University of Georgia (2000). She then went on to complete her Ph.D. in Brian Farrell's lab (2007) and spent four years as a postdoc in Hopi Hoekstra's lab (2007-2011), both in the Department of Organismic and Evolutionary Biology at Harvard University. She is currently an Assistant Professor in the Department of Biology at the University of Kentucky. When not in the lab, she enjoys spending time with her family (see "Honorary Lab Members" below).

PhD Candidate: Robin Bagley



Robin joined the Linnen lab at its inception in 2011, after completing her B.S. and M.A. at Kean University. At Kean, she worked on a variety of research projects until stumbling upon her true love, Neodiprion sawflies, in Dr. Sylvio Codella's lab. In her graduate work, she seeks to understand the role that divergence in host use plays in the formation of new species. She is currently supported by a USDA-NIFA predoctoral fellowship.

PhD Candidate: Kim Vertacnik



Kim completed her B.S. in molecular biology at Western Washington University (2010), where she worked on Rhagoletis speciation under Dietmar Schwarz. After graduation, she worked as a lab tech at Penn State in Kelli Hoover's lab, then joined the Linnen Lab in 2012. In her graduate work, Kim is using comparative genomics to investigate the genetic basis of host-use specialization in pine sawflies. Outside of Biology, Kim has work experiences ranging from retail to domestic violence advocacy. Much to the delight of her labmates, she also loves to bake.

PhD Candidate: John Terbot



John completed his B.S. in Evolution/Ecology and Entomology at The Ohio State University (2012). Joining the lab in 2013, he is studying the genetics and evolution of feeding aggregations, using Neodiprion as a model. Art is also very important to John. He particularly enjoys mixed media, digital, film, and video arts.  He is an advocate for collaboration and cooperation between art and science. Through these interactions, he hopes to learn new perspectives on scientific issues and communicate science to a broader audience.

PhD Student: Emily Bendall



Emily earned her B.A. in biology from Willamette University in 2013, where she worked on coevolution of yuccas and yucca moths in Chris Smith’s lab. She joined the lab in 2014. Emily is planning to study the genetic basis of divergent host-use traits in Neodiprion, and their role in speciation.

Postdoc: Danielle Herrig



Danielle earned her B.S. in Biology at St. Ambrose University (2010). During her PhD at the University of Iowa, she investigated the genetics of speciation utilizing Drosophila sister species to assess gene flow, gene expression divergence for different gene types, and the role of gene expression in hybrid dysfunction. Her work in the Linnen Lab focuses on characterizing gene expression across life-stages and in different tissue types to unveil the role of chemosensory gene expression changes in development, mate choice, and speciation. She enjoys spending her time outside of the lab hiking and exploring new places with her husband and hound.
