About us

Our mission is to research and teach how the collective behavior of molecules and cells forms the basis of life. We are driven by a passion for discovery and education and supported by cutting-edge research centers and state-of-the-art facilities on Harvard’s Cambridge campus.

Areas of research within MCB are highly diverse, ranging from the study of RNA structure, chromosome movement and cell wall synthesis, to membrane biogenesis, organ development and odor sensing. Our experimental systems are equally varied, ranging from viruses, bacteria and yeast, to Drosophila, C. elegans, zebrafish, and mouse.
