My research interest lies in fish ecology, primarily focusing on the effects of stress on growth and mortality. In my most recent work I have applied methods of analysis previously reserved for adult fish to data on growth and mortality of larval fish using detailed growth information recorded in the otoliths, or ear bones. This work is leading to new methods of stock identification, as well as methods for evaluating the effectiveness of large scale stocking programs. In addition to this I am investigating the causes of mortality of fish caught and released by anglers, the use of thermal refuges by striped bass and trout in marginal habitats.
