Research Summary
This program has evolved from the basic biochemistry and enzymology of glycoconjugate structurem function, and synthesis to the study of glycoconjugates in cartilage development, including the identification of gene defects in disorder of skeletal neurodevelopment and chondrodystrophies underlying pathophysiology of the matrix deficiencies. A second area of interest involves CNS development, and the role of gliogenesis and glial cell function in traumatic brain injury and developmental disorders.
