Teresa Hastings, PhD

  • Associate Professor
  • Director, Honors College Health Sciences Fellowship Program

Dr. Hastings was trained with a background in nutrition, oxidative toxicology and biochemistry specializing in protein chemistry and enzymology. The focus of her research has been investigating free radical formation and oxidative mechanisms associated with neurodegeneration as they relate to models of Parkinson’s disease and drugs of abuse, utilizing both animal and cellular models. Dopamine oxidation to reactive metabolites, protein modification, and the effect of the reactive dopamine quinone on mitochondrial function has been the specific focus of the Hastings’ lab. More recently, her laboratory has been investigating the neuroprotective role of selenoproteins in Parkinson’s disease.
