Bryan Ranger is the Ferrante Family Assistant Professor in the Department of Engineering, holds a courtesy appointment in the William F. Connell School of Nursing, and is a member of the Global Public Health and the Common Good Program faculty. At Boston College, he leads the Biomedical Imaging and Instrumentation Lab, where his research focuses on developing technologies that make healthcare more accessible and cost-effective, with particular emphasis on ultrasound and AI-based image analysis. His current work includes developing portable ultrasound tools for assessing body composition and nutrition in maternal and neonatal health. His research program has been supported by the National Institutes of Health (NIH), the National Science Foundation (NSF), the Gates Foundation, and Google. He is also committed to advancing engineering education through research and teaching, and teaches courses ranging from first-year engineering analysis laboratories to a biomedical imaging elective in the Human-Centered Engineering program.

Prof. Ranger works at the intersection of biomedical engineering and global public health. Throughout his career, he has contributed to global health initiatives including field research in Zambia and Uganda, and through programmatic and policy-oriented work with the World Health Organization and USAID. Immediately prior to joining the faculty at Boston College, he served as a Program Officer in the Global Health Division at the Gates Foundation, where he managed research programs and investments in medical devices, imaging, AI, and digital health. His lab currently conducts collaborative research with Jimma University in Ethiopia, Brigham and Women’s Hospital and Harvard Medical School in Boston, and the University of Minnesota Medical Center in Minneapolis. He is an IEEE Senior Member, serves on the IEEE Engineering in Medicine and Biology Society (EMBS) Technical Activities Committee (TAC) on Biomedical Imaging and Image Processing (BIIP), and chairs the Healthcare Task Force of the International Association of Jesuit Engineering Schools (IAJES).

Prof. Ranger completed his Ph.D. in Medical Engineering and Medical Physics at MIT through the Harvard-MIT Program in Health Sciences and Technology (HST) as a National Science Foundation Graduate Research Fellow. His dissertation focused on developing ultrasound imaging methods to improve lower-limb prosthesis design. While at MIT, he was also an instructor at the D-Lab. He earned his M.S.E. and B.S.E. in Biomedical Engineering, with concentrations in medical imaging and bioelectrics, from the University of Michigan.
