Biographical Information

Our research group explores the behavior, ecology and diversity of arthropod predators. We employ a broad array of approaches aimed to understand the mechanisms behind species coexistence patterns.  Spiders are the focus of most of the research in our group because they are a common, but very diverse, group of generalist predators and are relatively easy to manipulate both in the laboratory and the field.  On-going projects explore the competitive success of invasive predators, the effects of anthropogenic stressors on spider abundance and activity, the sensory priorities of spiders and their prey, and the behavioral versatility of spiders in response to predators, prey and conspecifics.  Creativity is encouraged in our research team and many students have initiated their own independent investigations that have led to new and interesting research directions.
