I am an evolutionary biologist who loves plants. I am especially interested in the ways that angiosperms distribute stamens and pistils among their flowers in order to specialize more on either the male or the female component of reproductive success. Specifically, I focus on andromonoecious plants, those that produce both bisexual and male flowers. My favorite plants are those in the parsley family (Apiaceae), ginseng family (Araliaceae), and spider flower family (Cleomaceae). I’ve studied these plants (and some others) in the Pacific Northwest, Rocky Mountain, and Northeastern US, New Zealand, and New Caledonia. I’m also working on a flora of the Vassar College Ecological Preserve and on digitizing the Vassar College Herbarium.
In the biology department, I teach introductory biology, Plant Diversity and Evolution (BIOL 208), Evolutionary Genetics (BIOL 248), Plants and Plant Communities of the Hudson Valley (BIOL 276), and Ecology and Evolution of Sexual Reproduction (BIOL 355). In environmental studies, I’ve taught Environmentalisms in Perspective (ENST 125), Native Americans and the Environment, and Environmental Science in the Field (ENST 254), in the American southwest and in Iceland. Ethnobotany is one of my academic “hobbies” so I’m happy to advise students who are interested in that field.
I’m working on development of the Vassar College Arboretum and Vassar’s class tree program. I’m also involved in the Poughkeepsie Farm Project, a CSA farm located on campus (farmproject.org).
