Martin-O’Neill fellow Christine Tataru uses computers to decode our guts

Christine Tataru receives the 2021-22 Larry W. Martin & Joyce B. O’Neill Endowed Fellowship for her work in computational modeling that seeks to understand how gut microbiomes impact their human hosts’ health. She develops tools and frameworks to advance microbiome research, then uses these tools to explore gut-brain axis phenomenon.
