James Mallet
Professor of Organismic and Evolutionary Biology in Residence, Associate of Population Genetics in the Museum of Comparative Zoology
(Not Accepting Graduate Students for 2024-2025)
Faculty Support: Nikki Hughes
We study evolution, hybridization, and speciation - mainly in butterflies. Methods range from collecting trips in dugouts, field experiments in the Amazon rainforest, population genetic inferences about selection and gene flow, and genomics. (Image courtesy of Tony Rinaldo)
