Some of My Research Interests:

My main research is in population genetics, conservation genetics, and biodiversity, especially in habitats that are affected by man-made stresses.  I am also greatly interested in speciation.  When are two groups of organisms considered different species and when are they considered the same species. A great example of this occurs in some dragonflies of the genus Epitheca (Tetragoneuria), the baskettails in the eastern USA.
I am studying the  genetics of dragonflies, including basic biodiversity measures, identification of species, genetic comparisons between populations, and using genetic profiles to classify individuals to species.  This work will give a firm base to other projects I'm planning for the future.
New York State is near the end of a multi-year project to inventory dragonflies and damselflies. The New York State Dragonfly and Damselfly Survey (NYDDS) is run through the New York Natural Heritage Program, a joint venture of NY Department of Environmental Conservation and The Nature Conservancy. I am the St. Lawrence Valley - Northwestern Adirondacks regional resource person for the NYDDS. Check out infomation about the survey by clicking on the image or go to the NYDDS homepage. Some information and research by my students can be found here.

I am also involved with the Adirondack Biodiversity Project (also called the Adirondack All-Taxa Biodiversity Inventory), which is a multi-partner project with the mission to survey the diversity of life in the Adirondack Park of New York State. Another goal of the project is to connect people to natural communities through participation in biological inventories. Check out their web page by clicking on the image or go to the Adirondack Biodiversity Project home page. Information specific to the Dragonfly Taxonomic Working Group of the Project can be found here.

I also have students that have worked on various genetic-related projects in my research lab. For more information, check out my research pages here.
