Jonathan Richardson
Assistant Professor of Biology

Jonathan integrates ecology, evolution and genomics to study applied issues related to urban ecology, epidemiology, and wildlife conservation. His research spans levels of biological organization and scale, from genes to phenotypes to communities, and populations to regional landscapes. Much of his work is in local urban environments, as well as Salvador, Brazil and New York City. More details can be found on his lab website.
