Secondary interests are with habitat alterations and aquaculture.
Research with Atlantic salmon continues to be a major focus of research, particularly with habitat selection by juveniles and the downstream migration of smolts. Research with movements of black basses has become a major area of research, particularly with radio telemetry. Future research will also involve other species of freshwater fishes and an estuary ecosystem study. Current research will deal with aspects of the freshwater biology of American eels and brook trout biology.
