My current research focus takes a translational approach to the assessment of neuropharmacological indices of stress-related disorders such as depression and irritable bowel syndrome (IBS). This approach incorporates studies in both clinical populations and in animal models using early-life stress templates that produce specific disease phenotypes in adulthood. I am particularly interested in advancing our understanding of how tryptophan degradation along the kynurenine pathway influences psychopathology and in evaluating novel therapeutic interventions which can reverse such deficits.
My research also interrogates the impact of microbiota manipulation on the central nervous system. This is a rapidly expanding area of research with enormous potential and one which is studied using the combined approach of germ-free animals, probiotic administration and antibiotic induced dysbiosis.
