Research

Description of Research Expertise:

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.
