The Cellular and Molecular Biology training program is headed by Daniel Rifkin, PhD, and includes 37 faculty members in six basic science departments. Training is offered in the general areas of structure, function, and biogenesis of macromolecules and organelles, as well as mechanisms that regulate cell metabolism, differentiation, and growth. The training program encompasses a strong representation in several areas at the cutting edge of cell and molecular biology, signal transduction, and molecular pathogenesis.
