A major question regarding the human gut microbiota is: by what mechanisms do our most intimately associated organisms affect human health? In this talk, I will present several systems-level approaches that we have developed to address this fundamental question. My lab has pioneered methods that leverage protein-protein interactions to implicate bacterial proteins in human pathways linked to disease, revealing for the first time a network of interactions that affect diseases such as colorectal cancer, inflammatory bowel disease, type 2 diabetes and obesity that can be mined for novel therapeutics and therapeutic targets. I will present novel methods that that enable deeper insight into the transcriptome of organisms within our guts and their spatial localization. Finally, I will shift to the problem of the spread of antibiotic resistance, in which the gut microbiota are implicated. Pathogens become multi-drug resistance by acquiring resistance traits carried by the gut microbiota. Studying this process in microbiomes is inherently difficult using current methods. I will present several methods that enable tracking of genes within the microbiome and computational tools that predict the network of gene transfer between bacteria. Overall, these systems-level tools provide deep insight into the knobs we can turn to engineer outcomes within the microbiome that can improve human health.

Ilana Brito is an Assistant Professor of Biomedical Engineering at Cornell University. Ilana received a BA from Harvard and a PhD from MIT. She started her postdoc as an Earth Institute Postdoctoral Fellow at Columbia University where she launched the Fiji Community Microbiome Project, a study aimed at tracking microbiota across people and their social networks, and continued this work at MIT and the Broad Institute working with Eric Alm. In her lab at Cornell, Ilana and her team are developing a suite of experimental systems biology tools to probe the functions of the human microbiome in a robust, high-throughput manner. Ilana has received numerous accolades for her work, including a Sloan Research Fellowship, Packard Fellowship, a Pew Biomedical Research Scholarship and an NIH New Innovator Award.
