Many of these focus on the importance of healthy eating and physical activity in weight management and in preventing and managing type 2 diabetes. He has been continuously funded from NIH since 1981 and in 1998 received a prestigious MERIT Award from NIH. He is the recipient of several ASN awards, including the Centrum Center Science Award, the McCollum Award, and the David Kritchevsky Career Achievement Award in Nutrition. He has received the TOPS award and the George Bray Founder’s Award from the Obesity Society. He was the 2012 Atwater Lecturer for the US Department of Agriculture.

Paul Maclean, PhD – Associate Director, Professor of Medicine
Dr. MacLean joined the UC Denver faculty in 2001 after receiving his training at Brigham Young and East Carolina Universities. His research efforts are focused on understanding the metabolic consequences of obesity and weight loss. He is funded by the National Institutes of Health to examine the metabolic adaptations to long term weight reduction that promote weight regain and strategies that facilitate weight loss by countering those adaptations. He works closely with a number of scientists in the Colorado Health and Wellness Center who perform clinical studies in this area. He has a number of interdisciplinary collaborations with other programs on campus investigating the metabolic complications of obesity. Dr. MacLean works with researchers in Reproductive Sciences studying the impact of obesity on mammary gland development and lactation. He works with members of the IMAGE Group (Investigations in Metabolism, Aging, Gender and Exercise) on clinical and preclinical investigating how obesity affects the menopausal transition. He also has a collaborative effort with several members of the University of Colorado Cancer Center to examine the link between obesity and postmenopausal breast cancer. These interdisciplinary research efforts have stemmed from facilitating the research enterprise on campus as the Research Director of the Division, the Director of the Energy Metabolism Program (affiliated with the Colorado Obesity Research Initiative), and as the Associate Director of both the Metabolic Core and the Energy Balance Laboratory (affiliated with the Colorado Nutrition and Obesity Research Center).
