Areas of Interest

Systematics, taxonomy, malacology, biogeography, ecology, biology education research.


This research integrates evolutionary biology and ecology, specifically applying the tools of molecular and morphological systematics and ecology to study taxonomy, ecology, conservation, and helicograph of terrestrial, freshwater, and marine snails. One major research project studies the systematics and taxonomy of the Polygyridae, a family of land snails in the United States and Mexico. A second research area is the study of the origin and colonization of the invasive freshwater snail Bithynia tentaculata. A third ongoing research project examines the distribution and diversity of local land snails using spatial analyses, geographic information systems (GIS), and environmental niche modeling. Finally, we are conducting several research projects on how students learn the nature and process of science and evolutionary concepts.
