Brief synopsis of current research:
My current research focuses on the analysis of data gathered during the prosecution of commercial fisheries to make inferences regarding fleet dynamics (temporal and spatial variation in fishing effort) and the biology of fish. Data from commercial fisheries will always have the potential to exceed the quantity of information affordably obtained from research surveys. However, it is critical that the circumstances underlying the collection of these data are understood to avoid confusion between natural and anthropogenic phenomena. To achieve this, my research focuses on the quantification of behavioral patterns of both fishers and fish contained within catch and effort data that may produce a biased representation of the fishery.
