Research Interests: I have broad interests in evolutionary ecology, including the evolution of plant mating systems, hybridization and the distribution and abundance of fungal endophytes in natural grass populations. I apply demographic modeling techniques to predict the population dynamics of symbionts in natural host populations under varying degrees of host gene flow.
Current Research (PhD) : I am currently investigating the coevolutionary dynamics between cool-season grasses in the family Pooideae and their vertically transmitted fungal endosymbionts. Specifically, I am interested in how gene flow alters host fitness and symbiont compatibility as well as host/symbiont long-term population dynamics. I use both experimental and population modeling techniques to address these questions in the field as well as the greenhouse.
Past Research (MA) : Elements of climate change, including increased variation in annual rainfall, may influence the evolution of plant mating systems and alter patterns of gene flow between species. As a Masters student in the Whitney lab I quantified the role of soil moisture on hybridization rates between two species of sunflower (Helianthus).
Additional Graduate Research: Distribution of fungal endophytes across an elevational cline: A study in an alpine grass (Poa alpina).
Undergraduate Research : As an undergraduate at the University of Nevada, Reno I became fascinated by gene flow between species and exploring what it means to be a “species.” In the Forister lab I was able to explore these questions by conducting a phylogenetic study on a largely unresolved species complex (Euphilotes pallescens). I found that evolutionary history is not always a clean branching process, but more like a web where branches cross and reticulate over time via gene flow.
