The work in my lab focuses on organismal plant ecology and physiology with a primary focus on ferns and their allies. Lab members work across many disciplines to include molecular biology, systematics, ecology, physiology, anatomy, and reproductive biology. I run a diverse ship, but the lab mainly focuses on how the natural world shapes the distribution of species in both modern landscapes and over evolutionary time frames. Central to our work are studies on plant stress physiology and developing a better understanding of the mechanisms behind stress tolerance and recovery.
