NSF Postdoctoral Fellow
Sara Miller
sem332@cornell.edu
Education:
B.A. University of Chicago
M.S. University of Missouri Saint Louis
Ph.D. (2016) University of British Columbia
Joined the lab in 2016
Research Interests: Understanding the role of biotic selection in adaptation, combining field experiments with genomics. Previous work examined adaptation to intraguild predation in sticklebacks as a PhD student with Dolph Schluter. Current work focuses on using population and comparative genomic approaches to understand adaptation and diversity in paper wasps.

Postdoctoral Researcher
Chris Jernigan
cmj92@cornell.edu
Education:
B.A. (2011) Biology & Chemistry, Butler University
Ph.D (2018) Animal Behavior, Arizona State University
Joined the lab in 2018
Research Interests: Understanding the interplay of phenotypic, behavioral, and neural plasticity. Chris’ dissertation work focused on how individual olfactory experience affects behavioral and neural responses to odors. His current work in the Sheehan lab focuses on understanding the neural and genomic mechanisms that give rise to individual signal recognition in paper wasps.
Study Organisms: Paper wasps, honey bees, stingless bees

PhD Student
Caitlin Miller
chm79@cornell.edu
Education:
B.A. (2014) Biology, Reed College
Joined the lab in 2016
Research interests: I’m interested in the genetic and neural basis of social behaviors. My research experiences have spanned a range of organisms and system levels, from studying baboon aggression in the wild to gene expression differences in astrocytes during neuronal maturation in cell culture. These experiences have driven me to be fascinated by the kinds of questions that you can ask at the intersection of behavior and neuroscience.
Study organisms: Mice
