Plant-Pathogen Interactions - Invasion Biology - Restoration Ecology - Seed Biology
My interest in biology is driven by my own curiosity and by my desire to help students understand biology not through memorization but through putting together the pieces for themselves—let’s call it thinking biology!
My research focuses on plant invasion biology from a community ecology perspective, including testing the Natural Enemies Hypothesis of invasion biology, spillover effects of a seed pathogen, and tools to facilitate restoration ecology. I have worked in the tropics, Midwestern forests, coastal beach communities and semi-arid shrub-steppe and grassland communities. My current goal is to explore whether naturally-occurring fungal enemies are a potential tool to control the invasive cheatgrass (Bromus tectorum).

My research focuses on plant invasion biology from a community ecology perspective, including testing the Natural Enemies Hypothesis of invasion biology, spillover effects of a seed pathogen, and tools to facilitate restoration ecology. I have worked in the tropics, Midwestern forests, coastal beach communities and semi-arid shrub-steppe and grassland communities. My current goal is to explore whether naturally-occurring fungal enemies are a potential tool to control the invasive cheatgrass (Bromus tectorum). I am investigating whether a naturally occurring seed pathogen, Pyrenophora semeniperda, can control cheatgrass. In addition, I am exploring other fungal pathogens responsible for natural stand failure (die-offs) on cheatgrass infested lands. Invasive species are an important threat to biodiversity, our economy, and at time even our health. I aim to help society and biologists to better understand some of our foremost invasive species.
