Current Research Interests:

Research in my group investigates interactions among plants and other organisms as an evolutionary game. In a game (e.g. checkers) your probability of winning the match depends on your strategy, and the strategy of your opponent. If you think about interactions in nature, these interactions really possess all the essential features of a game: the success of one organism depends on its traits, and the traits of the organisms (e.g. predators, competitors, mutualistic partners) with which it interacts. Research in the lab tends to focus on belowground interactions, but any biotic interactions can find their way into the lab! This includes resource competition among plants or microbes, resource trading among plants and mutualistic partners, or resources lost through attack by enemies such as herbivores or pathogens.

Research in the lab involves a mixture of empirical and theoretical tools to explore questions. Depending on the question, we might grow a plant in the greenhouse, charter a bush plane into the Canadian Boreal, or we might develop a mathematical model.
