William Caldwell

William Caldwell is a Professor at the Medical College of Georgia, affiliated with the Department of Pharmacology and Toxicology. Despite retiring as Chair of the department, he remains actively engaged in research and education, maintaining a funded laboratory focused on vascular and retinal dysfunction in metabolic diseases.

• Ph.D., Pharmacology, Emory University (1969)
• BS, Applied Biology, Georgia Institute of Technology (1965)

Research Interests: Dr. Caldwell investigates the role of L-arginine availability in reactive oxygen species formation, immune cell dysfunction, and vascular/retinal pathologies associated with diabetes and obesity. His work emphasizes arginase enzyme mechanisms in metabolic stress and angiogenic repair.

Recent Publications highlight his focus on diabetic retinopathy, vascular complications, and enzyme-based therapeutic strategies. Key themes include metabolic regulation, oxidative stress, and tissue repair pathways.

Teaching: He instructs graduate and medical students in courses such as Cardiopulmonary/Heme, Clinical Pharmacology Tutorial, and Seminar in Pharmacology, with a focus on cardiovascular pharmacology and physiology.

Laboratory: Maintains an active, funded research team exploring novel interventions for vascular and metabolic diseases.
