Overview

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 Overview

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 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.
