Cultural traits, behaviors that are learned from others, can change more rapidly than genes and can be inherited not only from parents but also from teachers and peers.
How does this complex process of cultural evolution differ from and interact with genetic evolution?
My research builds on knowledge about learned behaviors from linguistics, animal behavior, and anthropology by integrating techniques and data from population genetics. By combining empirical and theoretical approaches to the study of genetics and learned behaviors, my research program targets three fundamental questions:
(1) In what ways can learned behaviors change the course of genetic evolution?
(2) How much information about evolutionary history persists in learned behaviors?
(3) How do ecological factors, such as environmental and species interactions, affect the evolution of learned behaviors?
I address these questions by integrating the study of human linguistic and genetic variation, the evolution of learned birdsong in a genetic context, and theoretical and computational models of genetic and cultural evolution.

I am an Assistant Professor in the Biological Sciences department at Vanderbilt University. Contact me for more information about joining my lab as a student or postdoc!
Previously, I was a postdoctoral fellow in Marc Feldman's lab in the Stanford University Department of Biology. I received my bachelor’s degree from Harvard University, working with Christine Queitsch, and my PhD from the Rockefeller University, working with Fernando Nottebohm and Joel E. Cohen.
My research merges computational and theoretical approaches to the comparison of cultural and genetic evolution in multiple systems, particularly human language and birdsong.

I have developed software to enable pairwise comparisons of bird songs, both in audio characteristics (frequency, duration, etc) as well as syntax (motif and syllable structure).
The paper will be on the bioRxiv soon, but until then contact me if you're interested in using the software.
