The goal of the training program in Medical and Public Health Laboratory Microbiology (CPEP Program) based at Beth Israel Deaconess Medical Center in collaboration with Children’s Hospital Boston and the State Laboratory Institute is to train fellows to assume leadership roles in academic, tertiary care and or public health clinical microbiology laboratories. Philosophically we believe that this education is best accomplished through hands-on instruction in microbiological methods, direct participation in the consultative and administrative activities of the microbiology laboratory, and participation in activities of the infectious diseases, pharmacy, and infection control/hospital epidemiology departments. A further philosophical belief is that fellows should be trained in the thought process involved in furthering the knowledge in our specialty. Our ultimate goal is to train academic leaders in the specialty who will both lead microbiology laboratories, and also contribute at a scientific level to microbiology diagnostics and/or to our understanding of infectious diseases. Lastly, we strongly encourage involvement in research in our field and would consider it a mark of an outstanding fellow to take advantage of the many research opportunities available during fellowship training. During our program, fellows will also participate in activities of the Massachusetts State Laboratory Institute and Boston Children’s Hospital to ensure a comprehensive experience that also includes training in public health and pediatric microbiology.
