Research Interests

I am interested in the genetic and biochemical basis of host-microbe interactions, their regulation and outcomes. RESEARCH GROUP OVERVIEW: Gut  (and in certain disease states systemic health) is shaped by diet, environment and gut microbial changes as well as by host genetics.  The influence of these combined factors contributes to processes including gut development and homeostasis, immune function and local and systemic signalling in defining health outcomes.   My group dissects how these different and combined factors can impact health, disease and longevity. The group has focused on microbial host-metabolite and dietary modification that impact the host  (including drug uptake, adiposity, circadian rhythm, immune functions) with a particular emphasis on signalling processes to identity key areas for therapeutic approaches.  We apply targeted and untargeted metabolomic approaches, animal models, cell systems and bacterial molecular and cellular biology to address our questions.
