My lab is focused on understanding how bioactive lipids contribute to diet-microbiome and microbiome-host interactions.  We use techniques in molecular biology, mass spectrometry, microbial genetics, and genomics to understand the consequences of lipid transfer between host and the microbiome.  Specifically, we are interested in how lipid-dependent host-microbe interactions define the initial colonization and development of the infant gut microbiome with the goal of supporting microbiome-conscious early-life nutrition.
