"Research in the Payseur laboratory is motivated by intriguing and long-standing questions about the mechanisms of biological evolution. How does one species become two? How do organisms adapt to new environments? What determines the sex ratio of a population? What forces are responsible for trait variation within and between species? We use concepts and tools from genetics and genomics to address these questions. We study humans and house mice as model systems."
"My students and I pursue this research using a combination of theoretical models, laboratory experimental populations, and natural populations of organisms. The range of projects studied by my doctoral students is very diverse. The research of most of my doctoral students combines mathematical modeling with field and laboratory experiments."
"Students in my lab work on topics loosely organized around the evolution & ecology of interspecific interactions and the evolution of reproductive strategies, especially cross-fertilization. We are particularly interested in host-parasite coevolution and the evolution & ecology of virulence."
