Dr. Dunbar is interested in atherogenic dyslipidemia and its treatment, and has particular expertise in the mechanism of action and adverse effects of nicotinic acid (niacin). He has developed sophisticated objective techniques to quantify the physical stigmata of flushing from niacin. He combines these techniques with laboratory pharmacodynamic studies to elucidate the integrated physiology of the response to niacin.
Dr. Dunbar specializes in the treatment of cholesterol disorders, and practices in the Preventive Cardiology Clinic at the Pereleman Center for Advanced Medicine
