FORMER POSTDOCTORAL RESEARCHER
My research at the Mills lab is related to the functional characterization of genetic determinants in the consumption of human milk oligosaccharides, and other milk glycoconjugates, by the infant borne bifidobacteria. This is an interesting model of evolution that can be used for diverse applications in the food industry.
More broadly, my research interests are studies at the molecular level and applications of probiotics and prebiotics in the food industry, including genomic and transcriptomic tools; and studies of mammalian milks and the intestinal microbiota as a source of bioactive agents with a potential impact on human health.
