Research and Teaching Interests: Biology of Aging, Endocrinology, Obesity, Neurodegenerative disease

Office Hours: By appointment


  • M.D., Southeast University Medical School, Nanjing (China), Medicine
  • Ph.D., Southern Illinois University, Carbondale, Molecular, Cellular, and Systemic Physiology

Dr. Sun's laboratory is exploring the genetic control of aging in mammals and vertebrates. We are studying the endocrine mechanisms and nutritional factors for their effects on longevity and aging.

  • The physiological role of the somatotropic axis in the control of aging in mammals and vertebrates
  • The dietary factors on aging and longevity: calorie restriction vs. methionine restriction
  • Interventions studies of age-related diseases such as Diabetes and Alzheimer’s disease
Research Opportunities
I am accepting Master's and Ph.D. students in my lab. If you are interested in joining my lab, please send me an email (This email address is being protected from spambots. You need JavaScript enabled to view it.) that outlines your research interests, as well as your curriculum vitae.

  • Research Interests

    Dr. Sun's current research focus on nutrition and hormonal signals during early-life development can influence the long-term health and the development of age-related diseases. Learn more about his previous research.

    Learn more about Dr. Sun's research on his lab website. He is currently recruiting motivated postdoctoral fellows, graduate students, research associates, and undergraduates. Candidates from a variety of backgrounds will be considered, provided they make a compelling case for contributing to the objectives and goals of the lab. Learn more about these opportunities on the website.
