Dr. Curry’s research programme is a mix of applied and theoretical questions in fish ecology with an emphasis on hydrology (habitats) and the application of science to the management of natural resources.  Biological and hydrological connectivity is the theme of his research.  Brook trout are often emphasized including studies to better understand the ecology of anadromous and resident forms, population structure and production in NB streams and lakes, and the influence of groundwater and landscapes on trout habitats. 

Other species studied include smallmouth bass (trophic structure in lakes, impacts on native species), the threatened Lake Utopia dwarf smelt (COSEWIC), impacts of invading muskellunge in the Saint John River, and human impacts on coral reef fish communities with his collaborators at Centro de Investigaciones Marinas, Universidad de La Habana, Cuba. 

Dr. Curry has a growing research programme in the trophic structure of aquatic communities that uses benthic macroinvertebrate diversity and stable isotopes.  The NB Water Classification regulation’s model for assessing health of rivers based on hydrological and benthic community structure was introduced by his Postdoctoral Fellow, Dr. Wendy Monk.
