Description of Research Expertise

Research Interest
The function of molecular and genetic signaling pathways involved in the development of musculoskeletal tissues.

Keywords
Development, Regeneration, Genetics, Mouse, Signaling, Bone, Tendon, Cartilage

Research Details
My laboratory is interested in signaling pathways regulating development and homeostasis of musculoskeletal system. We use moues genetic models to study the function of ER stress, mTORC1, and Wnt signaling in bone, cartilage and tendon. I am also interested in the involvement of these signaling pathways in injury repair. Recent studies showed that developmental signaling pathways are involved in injury repair of musculoskeletal tissue. My laboratory combines several surgery models with mouse genetic models to investigate the function of signaling pathways in injury repair mechanism. Furthermore, my laboratory also studies the contribution of abnormal signaling pathways to the pathogenic mechanism of musculoskeletal diseases such as osteoarthritis, osteoporosis, and tendinopathy. I expect that my research programs will not only contribute to the understanding of musculoskeletal system and related repair mechanism, but also give insight into the advancement of regenerative medicine.
