Research Interest

Glycan immune recognition and response in health and in disease:
Our lab is studying the mechanisms that govern glycan immune recognition and responses in animal models and in humans, both in vitro and in vivo. We combine glycobiology, immunology, biotechnology and cancer research, and use cutting edge technologies within these disciplines, including glycan microarray and glyco-nanotechnology.

Current interests include:

  • Immunological mechanisms of unique anti-carbohydrate antibodies.
  • Anti-carbohydrate antibodies in mucosal secretions and sera.
  • Novel diagnostics and therapeutics to chronic inflammation mediated diseases.
  • Bio-nanotechnology tools based on glycan recognition.
