My laboratory works on treatments for metabolic and genetic bone diseases.  We use molecular genetic approaches in rodents to identify new ways to make bone stronger.  One particular approach that we have focused on is mechanobiology.  Mechanobiology merges the older science of mechanics with the newer and emerging disciplines of molecular biology and genetics.  At the center of mechanobiology is the cellular process of mechanotransduction, or the way cells sense and respond to mechanical forces.  We research how mechanical loads signal bone cells to build stronger bones.  Our research program has led us to the Wnt signaling pathway as a major regulator of mechanotransduction.  Current projects are centered around the particular steps in the Wnt cascade that are activated by mechanical stimuli and ultimately lead to increased anabolism.
