Dr. Cawthon received a doctorate in epidemiology from University of California, Berkeley. Dr. Cawthon's current research interests include maintaining mobility in old age;sarcopenia (age-related muscle loss); frailty; the decline of physical function with age;and osteoporosis, particularly in older men. Dr. Cawthon has several years of experience managing large, multi-center observational studies. She also oversees the statistical Analyst Group at the Coordinating Center

Research Interests

  • Maintaining mobility in old age
  • The epidemiology of sarcopenia, frailty and age-related physical decline
  • Translational approaches to studying sarcopenia, frailty and age-related physical decline
  • Osteoporosis in men
  • Vitamin D supplementation for the prevention of physical decline
