Although the world is green, the world is not peaceful; plants compete for resources and defend themselves against herbivores and pathogens. These interactions drive population dynamics and have the potential to lead to species loss as well as pest outbreaks. Currently, my research focuses on 1) plant-herbivore interactions and the potential to use plant defenses to control pests in agricultural systems and 2) competition between male and female plants and the loss of one sex. To quantify the relationship between these interactions and population dynamics, I use a range of tools from laboratory experiments and field-collected data to mathematical models and computer simulations.
