Overview The Department of Molecular and Cell Biology offers a program of graduate study leading to the PhD in molecular and cell biology. This program provides advanced training in the research methods and concepts of the study of the molecular structures and processes of cellular life. The training is intellectually focused, but at the same time offers an unusually wide range of opportunities for varied disciplinary specialization. The teaching and research activities of the Department of Molecular and Cell Biology (MCB) concern the molecular structures and processes of cellular life and their roles in the function, reproduction, and development of living organisms. This agenda covers a broad range of specialized disciplines, including biochemistry, biophysics, molecular biology, structural biology, genetics, genomics, bioinformatics, cell biology, developmental biology, tumor biology, microbiology, immunology, molecular medicine, and neurobiology. The types of living organisms from which the departmental faculty draws its working materials are as diverse as its disciplinary specializations, ranging from viruses and microbes through plants, roundworms, annelids, arthropods, and mollusks to fish, amphibia, and mammals. The faculty is organized into six divisions: Biochemistry, Biophysics, and Structural Biology; Cell Biology, Development, and Physiology; Genetics, Genomics, Evolution, and Development; Immunology and Molecular Medicine; Neurobiology; and Molecular Therapeutics.
