New CAS biochemist investigates vitamin B12’s impact on the gut
BIOCHEMISTRY, CHEMISTRY — Romila Mascarenhas, assistant professor of biochemistry, is starting a lab that investigates how gut bacteria recognize, transport and use vitamin B12, a molecule that plays a huge role in shaping microbial communities in the human gut. She anticipates her research will lead to collaboration with fellow CAS researchers across disciplines and attract a new generation of STEM students.
