Research Interests

Evolutionary Ecology

I study natural selection and ecological processes, including rapid, evolutionary effects of gene flow (especially involving transgenic plants). I also investigate possible risks associated with gene editing and gene drives for altering or suppressing wild populations. A current example involves a proposal to develop gene-edited, white-footed mice that are resistant to Lyme disease for Martha’s Vineyard and Nantucket, Massachusetts. Evaluating this proposal led to my latest research project as an emeritus professor, which is investigating the abundance and infection levels of blacklegged ticks on Nantucket, to better understand the ecological dynamics of the Lyme transmission cycle.
