We are studying the biological components of the aging process to develop targeted strategies that help maintain and promote good health. We’re addressing the aging body’s increasing inability to respond to internal and external factors such as bone fractures, drug interactions and infections. We also explore the impact nutrition plays in reducing vulnerability to these stresses.
