Annie Caldwell PhD

Assistant Professor, Division of Endocrinology, Metabolism and Diabetes, University of Colorado School of Medicine


Dr. Caldwell received her PhD, BS and MS from the University of New Mexico and began her Ludeman Center-funded research in 2022. With so many gaps in knowledge around women-specific issues, she was driven to improve people’s health and well-being and committed to help broaden our scope of knowledge. 


Research + Funding 

Dr. Caldwell’s project titled, “Effects of Controlled Energy Restriction on Pituitary Function and Psychological Stress in Normal Weight Women and Women with Obesity,” focuses on the need to better understand the various causes and implications of reproductive axis suppression to improve women’s health across the reproductive lifespan and beyond. This Ludeman Center seed grant study will be the first to test the effects of a controlled low-energy diet on pituitary function in women with obesity as well as women of healthy weight. The results will lead to a better understanding of the extent to which energy restriction inadvertently leads to reproductive axis suppression, to improve women’s health across the reproductive lifespan and beyond.  


Transforming Women’s Health 

"It’s wonderful to work with an organization with a shared mission and vision, incredible to meet the other Ludeman Center scientists and the amazing work they are doing, and the training and support have helped me tremendously,” Dr. Caldwell shares. Her current research priority is understanding factors that make healthy weight management more difficult for women and approaches to overcome these difficulties to improve women’s health and well-being.
