Research Interest

His research interests are in the field of behavioral ecology, more specifically predator-prey dynamics and sexual selection. Work in thier lab over the last several years has focused on the round goby, an invasive species of fish from Eurasia. Thier work involves quantifying predation by round goby on dreissenid mussels (zebra and quagga mussels), determining the size of dreissenids preferred by goby, and exploring the factors influencing size-selectivity by goby. They are also working with the pharyngeal apparatus of round goby, which functions like another set of jaws in crushing mollusk prey. In addition to that work, They have also described and characterized vocalizations made by male round goby and they hope to elucidate the information content of those sounds. More recently, They have begun investigating reproductive investment in the spiny water flea, an invasive species of zooplankton from Northern Europe and Asia, and how variation in offspring number relates to female size and age. In the summer of 2012, They began investigating ontogenetic changes in food habits and pharyngeal apparatus of bluegills, pumpkinseeds and their hybrids.
