Nick is a behavioral ecologist that studies infectious disease. He is a self-admitted study system collector (17 species so far!), with an inordinate love for invertebrates. He is also a mega-nerd, juggler-in-training, and loves heavy metal.
Postdoctoral researchers

Emily Durkin, PhD
Evolutionary Ecology of Symbioses
email: edurkin [at] ufl [dot] edu
Emily is fascinated by symbioses and why they evolve. She is particularly fond of parasitic relationships, especially from the perspective of the parasite. Emily completed her MSc. at Northern Michigan University studying chewing lice (Pthiraptera) of brown-headed cowbirds (Molothrus ater). Her Ph.D. research was completed at the University of Alberta in Canada and explored the ecology and evolution of parasitism using a facultatively parasitic mite (Macrocheles muscaedomesticae) and fly host (Drosophila hydei), employing experimental evolution to select for increased attachment behavior in the mites and studying its associated costs and benefits. She is currently exploring parasite behavior and its role in the evolution of symbioses.

Allison Roth, PhD
Consequences of Animal Sociality
email: allisonroth [at] ufl [dot] edu
Allison is a behavioral ecologist who focuses primarily on questions related to sociality. Allison obtained her MA from Columbia University, studying between group encounters in blue monkeys (Cercopithecus mitis). Allison went on to complete a PhD at the University of Oxford where she explored the intersection between animal personality and sociality, using a dual study system of great tits (Parus major) and red junglefowl (Gallus gallus). She is currently exploring the prevalence and consequences of avian blood parasites in California quail (Callipepla californica) using social network analyses.
Graduate students

Steven Cassidy
email: stevencassidy [at] ufl [dot] edu
Steven is a PhD student interested in how behavior can influence species interactions. He completed his B.S. in Ecology and Evolution at the University of Pittsburgh studying plant ecology. As an undergrad, Steven studied mutualism disruption in understory plants, and then worked as a lab technician studying how herbivory impacts the evolution of the plant root microbiome. He has also worked with the African social spider Stegodyphus dumicola. He plans to study how the nature of species interactions can covary with behavior and diseases.
Elise Richardson
email: ear6296 [at] ufl [dot] edu
Elise is a master's student interested in behavioral disease ecology in insects and wildlife. She graduated from the University of Florida with a bachelor's in wildlife ecology and conservation and a minor in entomology. She has worked with the CDC studying pesticide resistance in lone star ticks (Amblyomma americanum) on white tailed deer and in the Entomology and Nematology Department studying mosquitoes and biorational larvicides. She plans to study the role of behavior in the vector capacity of various necrophagous and hematophagous flies.

Sam Shablin
email: samanthashablin [at] ufl [dot] edu
Sam is an NSF Graduate Research Fellow who received her B.S. in Ecology & Evolution and B.A. in History from the University of Pittsburgh. As an undergrad, Sam worked with the fungal pathogen Bd, and its interactions with glucocorticoids and frog behavior. During her PhD, she plans to study how an individual’s social behavior impacts their susceptibility to disease and how behavior may underlie both interspecific and intraspecific transmission, especially among more susceptible native species and more resistant invasive species. Outside of the lab, Sam enjoys scuba diving and taking her lizard for walks. Sam is co-advised by Dr. Ana Longo.

Tim Colston, PhD
Affiliate Faculty Member, Department of Biology, University of Florida
Tim is a herpetologist by training, but his research integrates biogeography, evolutionary ecology, and host-microbiome interactions. Tim collaborates with the Keiser Lab on a project focusing on venom evolution and venom-associated microbiomes in social spiders.
