Congratulations to the Graduating Class of 2026!
The College of Arts and Sciences’ divisions will hold commencement ceremonies on Monday, June 15, 2026.
The Story of B-12
Inside the human gut, billions of microbes compete and cooperate for survival. For many of them, access to a single nutrient — vitamin B12 — determines who thrives and who doesn’t.That microscopic competition is the focus of research led by Romila Mascarenhas, a new assistant professor in the College of Arts and Sciences Department of Chemistry and Biochemistry.
Mascarenhas' work 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.
