About Molecular and Cellular Biosciences (MCB)

The Division of Molecular and Cellular Biosciences (MCB) supports fundamental research at the intersection of disciplines to uncover the emergent properties of complex living systems across the molecular, subcellular and cellular scale.  The Division welcomes proposals that incorporate theories and concepts from physics, mathematics, chemistry, engineering and computer science in search of the most fundamental Rules of Life, as well as proposals that offer technological innovations to enable the multi-disciplinary research enterprise.
