Research Interests

My research interests include (1) paleoecology and taphonomy with emphasis on the process of preservation and destruction of carbonate skeletal material in marine sediments, (2) population dynamics modeling with emphasis on the modeling of shellfish diseases, genetics-based modeling focused on relating genotype to phenotype and environment, the application of models to estuarine management, and fisheries modeling emphasizing approaches to stock sustainability, (3) fisheries management emphasizing approaches to discard reduction, improvements in survey methods, and evaluation of alternative management approaches, and (4) the interaction of contaminants, parasites and pathologies in bivalve health.
