My research interests include Population Genetics, Molecular Ecology, Conservation Genetics, Ecological Genetics, and Evolutionary Ecology. I am mainly interested in studying the roles of both adaptive and non-adaptive microevolutionary processes in population structure, genetic diversity, phenotypic evolution, and speciation. My research has generally focused on invasive species, rare and endangered species, and recently evolved species complexes.
I am currently setting up a new laboratory at UTC for the study of population genetics and evolutionary biology.
