As a researcher, I am fascinated by the population biology of plants. My work has primarily been in three areas: 1) studies of the ecology and evolution of plant-fungus and plant-virus interactions, 2) research on the population dynamics of wild sunflowers, and the ecology and genetics of hybridization between crop and wild plants, and 3) long-term demographic studies of a rare prairie plant, Mead’s milkweed, including using “mark recapture” models to estimate population size, detectability, and probability of survival. As an educator, I teach courses in conservation biology, biostatistics, and research methods. I have been fortunate to win several teaching awards, including a Chancellors Club Teaching Professorship. Finally, my outreach and service activities often involve outdoor education and interactions with secondary school science and math teachers.
