Current Research Interests:

Dr. Freeman's research efforts are focused on investigating the adverse effects of environmental stressors on human and environmental health using the zebrafish model system. Current research projects include (1) defining the influence of environmental stressors on genomic instability and carcinogenicity, (2) investigating the role of structural genetic variation in response to exposure to environmental stressors, and (3) identifying the role of environmental stressors in the onset of neurodegenerative disorders.
