The Graduate School of Biomedical Science & Engineering (GSBSE) offers a doctoral degree in Biomedical Engineering. The GSBSE contributes to learning and discovery on the ''emerging frontier'' of the biological, physical, clinical, and behavioral sciences, preparing new faculty, training scientists and engineers, and furthering Maine's biotechnology and biomedical infrastructure. Students admitted to the GSBSE can choose a dissertation mentor from over 150 faculty located at any one of these world-class research and educational institutions. Student access to courses, as well as faculty, is achieved through a high-end videoconferencing system. Toxicology is an applied discipline that incorporates and builds on a host of scientific disciplines to investigate the consequences of exposure to chemical agents on living organisms and the environment, and the cellular and molecular mechanisms that underlie those consequences. Research strengths of the GSBSE include comparative marine toxicology, chemical carcinogenesis, immunotoxicology, toxicogenomics, neurotoxicology, and outer space toxicology.
