Research Focus


My research focuses on understanding how the mechanical environment influences bone adaptation and regeneration during growth, skeletal maturation, and aging. Specifically, I am investigating the regulation of modeling and remodeling processes by mechanical loading and the role of osteoblastic cells (osteoblasts and osteocytes, the primary sensor and effector cells of mechanical cues) in mechano-sensation processes. My research involves in vitro, in silico, and preclinical in vivo models as well as clinical trials to investigate the mechanism(s) responsible for the skeletal response to mechanical stimuli.
