Dr. Tuan directs a multidisciplinary research program that focuses on orthopaedic research as a study of the biological activities underlying the development, growth, function, and health of skeletal tissues, and the utilization of this knowledge to develop cell-based technologies that will regenerate and/or restore function to diseased and damaged skeletal tissues. Ongoing research projects are directed towards skeletal development, stem cells, growth factor signaling, bone-biomaterial interaction, extracellular matrix and cell-matrix interaction, nanotechnology, mechanobiology, regenerative medicine, and tissue engineering, utilizing integrated contemporary technologies of biochemistry, cell and molecular biology, embryology and development, cellular imaging, and engineering.
