Research Interests

My research focuses on how variation in plant traits drive, and are driven by, biotic and abiotic interactions. I use intraspecific variation in functional traits to evaluate how local populations are adapted to specific stressors, including herbivory, salinity, and cold tolerance. I utilize both observational and experimental techniques to evaluate local adaptation and phenotypic plasticity and their effects on local biodiversity.
