Research Interests

Dr. Yu's current research includes the study of complex glycoconjugates, particularly glycosphingolipids, play crucial roles in determining cellular properties, such as intercellular interactions, recognition and adhesion. He and his staff are developing an understanding of the role of stage-specific glycoconjugates in governing cell events via several signaling pathways. His current projects are focused in the following areas:

  • Developmental neurobiology the role of glycoconjugates in cellular proliferation and differentiation as well as the metabolic basis and regulatory mechanisms for changes in their expression in normal brain development;
  • Stem cell biology role of glycoconjugates in neural stem cell differentiation and proliferation as well as use of stem cells in transplantation therapy;
  • Mechanisms of neurodegenerative disorders the basic mechanisms underlying a variety of neurodegenerative disorders, including neuroplasia, multiple sclerosis, autoimmune demyelinating neuropathies, mucopolysaccharidoses, sensorineural hearing loss, Parkinson's disease and Alzheimer's disease
  • Neurooncology basic mechanisms of tumorigenesis and development of vaccine-based tumor suppression strategies.
