Department faculty conduct cellular and molecular research to study basic biology and the origins and treatments of human disease. Among their targets are protein, metabolic and genetic controls of disease, and cell growth and differentiation in various biological systems, including skin, hair, fat and sensory nerves. Faculty member Dr. Peter Agre was co-recipient of the 2003 Nobel Prize in Chemistry for his lab's discovery of aquaporin water channels. Faculty are associated with the Biochemistry, Cellular and Molecular Biology Graduate Program, the Graduate Training Program in Cellular and Molecular Medicine and the Predoctoral Training Program in Human Genetics.
Since the 1940s, this department has applied advanced engineering technologies and concepts to biological problems and human diseases in seven research areas: engineering, cardiovascular systems, imaging, systems neuroscience, molecular and cell systems, neuroengineering and computational modeling. The formation of the Whitaker Biomedical Engineering Institute in 1999 and the faculty's close ties with the Center for Hearing and Balance, the Mind/Brain Institute, the Applied Physics Laboratory and the Center for Cardiovascular Bioinformatics and Modeling encourage a multidisciplinary, collaborative approach to research. The department has its own Master of Science, doctoral and postdoctoral training programs in biomedical engineering.
Biophysics and Biophysical Chemistry
For more than 40 years, this department has applied quantitative biophysical methods to the analysis of macromolecular structures and biological systems. Faculty members use a wide range of research tools, including X-ray crystallography, nuclear magnetic resonance (NMR) and fluorescence spectroscopies, computer modeling and theory, and structure-activity studies. Researchers investigate enzymes, antibodies, cell-surface receptors, ribosomes, data from the genome sequencing project, and DNA-, RNA- and metal-binding proteins. Faculty members are associated with the Biochemistry, Cellular and Molecular Biology Graduate Program and the Program in Molecular and Computational Biophysics.
Molecular and Comparative Pathobiology
With its strong emphasis on animal models of human disease and long history of producing leaders in academic and industrial settings, this department is a national leader in research on animal diseases and animal models of human diseases. Research topics include animal models of AIDS, cancer, neurodegenerative disease, cardiovascular disease and inflammatory lung disease. Faculty, fellows and residents control disease outbreaks in the institutional animal colonies through the division of Molecular and Comparative Pathology and provide clinical care of research animals through the Research Animal Resources division. The department’s Retrovirus Laboratory oversees a training grant in pathobiology for pre- and post-doctoral trainees to study the molecular pathogenesis of lentiviral diseases.
Building on the department's long, rich history, faculty members merge molecular biology and microscopy techniques to focus on cellular form, function and transformation. Departmental scientists study topics including cell motility, adhesion and formation, with tools like scanning and transmission electron microscopes, peripheral quantitative computed tomography, full-body CT scanners, and 3D time-lapse video imaging. Faculty participate in the Biochemistry, Cellular and Molecular Biology and the Johns Hopkins University Biology graduate programs.
Molecular Biology and Genetics
Department members' research projects include gene expression and regulation, the cell cycle, signal transduction, developmental biology, microbial pathogenesis, immunology, DNA transposition, telomeres, RNA catalysis and the molecular biology of vision and olfaction. Many faculty members are Howard Hughes Medical Institute investigators. Former faculty members Hamilton Smith and the late Daniel Nathans received the 1978 Nobel Prize in Physiology or Medicine for their discovery and use of site-specific restriction enzymes. Faculty participate in eight School of Medicine graduate programs.
Neuroscience faculty focus on four main areas: molecular, cellular, and developmental neurobiology, systems neuroscience, cognitive neuroscience and the neurobiology of disease. Many faculty have joint appointments in other departments. Specific research topics include the mechanisms of learning and memory, neurotransmitters and growth factors, the visual system, synaptic plasticity, behavioral biology, neurodegenerative and neuropsychiatric disorders, adult neural stem cells, vestibular system function, motor control, and neuronal death, survival and regeneration. Faculty participate in the Neuroscience and Biochemistry, Cellular and Molecular Biology training programs. Learn more about the Neuroscience NIH Initiative: Conte Center.
Pharmacology and Molecular Sciences
John J. Abel, the "Father of Pharmacology," founded this department in 1893. Current faculty members are experts in biochemistry, immunology, virology, cancer, neuroscience, metabolism, genetics, and biophysics. Specific research topics include chemoprevention of cancer, viral mechanisms, protein structure and function, gene therapy, vaccine development, histone acetylation and gene regulation, drug metabolism, melatonin and circadian rhythm, and immune system activation. Faculty accept students from the Anti-Cancer Drug Development Training Program, the Biochemistry, Cellular and Molecular Biology Graduate Program, and the Medical Scientist Training Program.
Researchers in the Department of Physiology integrate many disciplines to understand the functions of individual systems within a whole organism and the mechanisms that produce and sustain life. Faculty tackle issues such as the molecular control of cell membrane activities, intercellular and intracellular communication, coordinated cell signaling for organ development and mammalian embryonic development. They use computational methods, genetics and post-genomic strategies to study these issues in a variety of organisms, from bacteria and yeast to zebrafish, mice and people. Faculty participate in a number of graduate programs, including the program in Cellular and Molecular Physiology.
