I’m a lucky guy. I’ve been able to convince some great people to come work in the lab. The people listed on this page are the real drivers of the research in our lab. I just do my best to stir up some money, provide mentorship when needed, and stay out of the way. It’s probably a bit more detailed than that, but it’s how I think about it. If you’re interested in learning more about the lab, send me an email, or email one of the folks below. If you want to know a little bit more about me, here’s my CV.

 

Justin Kratovil, PhD (2017)

UK: Fall 2010 - Spring 2017

Before UK: Hartwick College (B.S.), Smith College (M.S.)

After UK: Postdoc with Jennifer White in Entomology at UK, Current postdoc with Elizabeth Jockusch at UConn.


Justin’s research focused on the genetics and behavior of speciating lineages and the evolution of reproductive compatibility. Using a combination of amplicon and ddRAD sequencing, and experimental mating trials, Justin tested hypotheses of species boundaries and gene flow among Desmognathus salamander populations in the Appalachians and isolated mountains in the Piedmont of North Carolina. Justin was awarded an NSF DDIG grant in 2014 to study the nuclear correlates of biased mitochondrial DNA introgression

This work has a particular focus on how populations maintain or lose connectivity in response to changes in glacial mass. More recently, Scott’s work has extended to similar questions in alpine microbial diversity.

Schyler’s interests are in changing population demographics over very recent time scales, and how these changes can be detected using genome-scale data sets. Schyler is using salamander species and multi-year genetic sampling to test for these shifts in a coalescent framework. In addition to this empirical work, she is building new models to account for the greater complexity that exists in the demographics of amphibian species. Schyler was awarded an NSF DDIG in 2016 to extend her work to a metapopulation level.
