Interests

Research Focus

Immunology; immunopathology; immunophysiology; mucosal immunology and its alteration in a variety of disease models; the role of neuroimmune interactions in allergy and inflammation; the reciprocal communication between the nervous system and immune systems; mechanisms of action of commensal bacteria on the nervous system and behaviour and in various models of inflammation.

He has made siginificant contributions in medical research.  Among these are: Mucosal immunology; neuroimmunology; mast cells, and psychoneuroimmunology.

His current projects include: functional role of mucosal mast cells; mechanisms of action of commensal bacteria in models of asthma, colitis and visceral pain; effects of commensal bacteria on cognition and behaviour; neuroimmune mechanisms.

He has published more than 500 peer-reviewed articles and other publications; authored, edited and co-edited 8 books including the standard text on mucosal immunology.
