I received my Bachelor’s degree in Genetics from Texas A&M University in 2012 and my Ph.D. in Evolutionary Biology from the University of Illinois in 2017. I was a postdoc at The University of California – Merced in the Department of Molecular and Cell Biology and Brown University in the Center for Computational and Molecular Biology and the Department for Ecology, Evolution, and Organismal Biology. In 2023 I joined the Clemson University Department of Genetics and Biochemistry and the Center for Human Genetics as an assistant professor.

Research Interests

I am a computational biologist and population geneticist who is interested in using ancient DNA to reconstruct the history of movement and interactions between human populations and their domesticates. My primary focus is on domesticated populations and how they can be used to understand past human migrations and diets. My past work has examined how dogs can be used as a proxy to understand migration and diet in human populations in the Americas. More recently I have begun to study the history of cattle in East Asia, focusing on Mongolia and China. I am also interested in past interactions between modern humans and archaic human populations, such as Neanderthals and Denisovans. To do this, I have studied how archaic variants are distributed across the genomes of modern individuals, and how they differ between global populations. I have also examined specific genes with archaic ancestry that have an important functional purpose in modern humans, to explore how past archaic gene flow events affect modern humans today.
