Research Interests

Understanding the adaptive response of bone to altered mechanical loading, including bone's mechanosensory system;  investigating interstitial fluid flow in bone as a possible mechanism of mechanical signal transduction;  quantifying the effects of estrogen deficiency and disuse on the osteocyte microenvironment;  using mechanical loading to enhance drug transport to bone tumors.
