Current research and/or projects

My research focuses on factors affecting productivity in groundfish species. Specifically I am attempting to understand the factors that affect growth, condition, maturation and fecundity. These are all critical to determining the level of fishing a population can sustain and in determining the length of time it will take depleted populations to recover. There are also important implications for interactions among different components of the ecosystem.

In addition, I am trying to determine how to quantitatively integrate this information into scientific advice to fisheries management. As an important part of this aspect of my work I am actively involved in the stock assessment of a variety of groundfish populations, both nationally and internationally through the Northwest Atlantic Fisheries Organization (NAFO).
