Professor, Senior Research
Dr. Stubblefield is an internationally recognized expert in the field of environmental toxicology, with a research focus on the area of aquatic toxicology and ecotoxicology. Previously an adjunct faculty member, Dr. Stubblefield has recently joined EMT (Sept. 2009) full time and will be continuing his research in the general area of environmental toxicology and the effects of chemicals and/or environmental stressors on ecological receptors. Ongoing research activities focus on the evaluation of metals and hydrocarbons in terrestrial and aquatic environments. Dr. Stubblefield's current projects are targeted toward conduct laboratory-based studies to determine the mechanistic basis for the effects of metals on aquatic organisms. This data is then utilized to develop deterministic models that can be used to predict toxicant bioavailability and potential effects on receptor organisms. The long term goal for Dr. Stubblefield establishes a Center of Excellence in the field of Environmental Toxicology at OSU.
Dr. Stubblefield will continue to participate in the training of graduate students (M.S. and Ph.D.) in the general fields of environmental toxicology and risk assessment, and serve as major professor and mentor graduate students. He will also train undergraduate students in the general fields of environmental toxicology and risk assessment (didactic and experiential leaning environments) in his research laboratory. Dr. Stubblefield will also continue to teach didactic courses in the general fields of environmental toxicology:
Environmental and Molecular Toxicology (411/511; 412/512;413/513)
Environmental Forensic Toxicology (TOX 455/555)
Environmental Toxicology and Ecotoxicology Seminar (TOX 607)
