Center Services

The Comparative Organismal Energetics Core (COEC) provides consultation in methods and study design, training, expertise and state-of-the-art instrumentation to facilitate research on the role of whole animal energetics and metabolism in aging. The core provides state-of-the-art instrumentation and analyses for quantifying energy balance and body composition in animals. This includes measures of energy expenditure (via indirect calorimetry), food intake, activity, and core body temperature. Body composition analyses can be performed on living and dead animals. Learn about our full list of services and COEC fees.
