Michael Stout, PhD

  • Assistant Professor

(405) 271-1617

Research Interests:

  • The central focus of Dr. Stout’s research program is to understand how metabolic disturbances promote aging processes and the onset of chronic diseases. He is particularly interested in the role that sex hormones play in regulating aging and disease due to sex-specific disparities in metabolic disease, inflammatory disorders, and healthspan across the life-cycle. The long-term goal of Dr. Stout’s laboratory is to develop therapeutic strategies that target metabolic signaling pathways in a manner similar to calorie restriction, thereby diminishing age-related diseases and compressing the period of morbidity in mid-to-late life.
