Dr. Hallerman researches population genetics of fish and wildlife species, genetic improvement of aquaculture stocks, aquaculture biotechnology and related public policy, and genetics education.
Dr. Hallerman’s research emphasizes practical application of genetic principles within the fields of population genetics, aquaculture genetics, and biotechnology. His team observes and analyzes variation of mitochondrial DNA, microsatellite DNA, and other nuclear DNA markers, and supports interdisciplinary application of population genetics in management of fisheries, wildlife, and other species.
His work includes the delineated management units for freshwater mussels, horseshoe crabs, and brook trout. His team has helped to restore the native New River strain of walleye. By developing risk assessment and risk management tools and by conducting empirical risk assessment research, Hallerman has contributed to sustainable development of aquaculture biotechnology.
He has also designed and initiated a selective breeding program for tilapia that is maintained by a private company.
