Brief synopsis of current research:
I focus on predator-prey interactions involving fishes. Current research is examining several questions. How do fish integrate information from multiple senses when making decisions involving the risk of predation? For a fish as a predator to consume its prey, it must normally be much larger than its prey. What are the physiological and ecological costs associated with this variation in size, and how does it affect their ability to use different microhabitats? I am also working with genetically modified fish that have had their growth rates dramatically altered. These animals are very useful for gaining insight into the costs and benefits associated with different growth rates. This research area also allows me to begin studying the potential environmental risk posed by these animals.
