Dr. Christopher S. Stoj
Associate Professor of Chemistry; Chair of Department
- Office Location:
- Golisano Center, room 246
Dr. Stoj teaches biochemistry and general chemistry.
Dr. Stoj is fascinated by the structure and function of proteins involved in the maintenance of metal ion homeostasis in biology, specifically as they relate to various neurodegenerative disease states. The aims of his research group are to better understand the complex nature of metal ion cofactors in biological health and disease states. The critical requirement for metal ions in biology has been known for many years and is typified by the red pigment of human blood as a result of oxygenated iron-loaded hemoglobin. Currently, altered metal ion homeostasis is considered a causative agent of many disease states including those of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Amyotrophic Lateral Sclerosis, also known as Lou Gehrig’s disease. We employ current biochemical and biophysical research tools to examine metal ion relationships to cardiovascular and neurodegenerative disorders, anemia, diabetes, as well as probe the mechanisms by which proteins and enzymes uptake, store, and mobilize metal ions.
