Student Research Opportunities
Students in my lab work on a variety of projects. Some contribute to ongoing projects while others develop their own. Most focus in one way or another on the ecology and evolution of plants, though I'm happy to advise or co-advise students working in any taxonomic group or system. If you are interested in conducting research in my lab please don't hesitate to contact me so we can discuss our mutual interests; I'm always interested in talking with intellectually curious and motivated students. Some ongoing and past projects include:
Floral mimicry in two California wildflower endemics (Clarkia gracilis ssp. tracyi and Sidalcea diploscypha).
Parasitic effects of dodder (Cuscuta californica) on several species of California annuals.
Mating system ecology of Clarkia growing along edaphic (serpentine) gradients.
Genetic basis and ecological significance of floral color polymorphisms in two subspecies of Clarkia gracilis.
Inbreeding depression, polyploidy, and the evolution of mating systems in the genus Clarkia.
Polyploidy and range size/niche breadth in the California flora.
Inbreeding depression in central and peripheral populations of Campanulastrum americanum.
Reproductive ecology of diploid and tetraploid Galax urceolata.
Maternal and paternal effects in Sinapis arvensis.
Influence of male and female environments on fertilization success in Brassica.
Botanical census of Schmeeckle Reserve (UWSP's 280-acre nature reserve).
Effects of exotic invasive species on native species diversity.
Pedagogical approaches to teaching ecological and evolutionary concepts.
