Samuel I. Miller is a Professor of Medicine, Microbiology, Immunology and Genome Sciences at the University of Washington. He has been the Director of the NIAID Northwest Research Center for Excellence in Biodefense and Emerging Infectious Diseases since its inception in 2003 and of the University of Washington Enteric Research Investigative Center of NIAID since 2010. He is the past Director of the Cystic Fibrosis Research and Development Program at the U W. He received his B.A. from John Hopkins University in 1975 and M.D. in 1979 from Baylor College of Medicine and was an Intern, Resident, Fellow, Assistant and Associate Professor at the Massachusetts General Hospital and Harvard Medical School. His research training was in the laboratories of Dr. Dyann Wirth (Harvard School of Public Health, molecular parasitiology) and Dr. John Mekalanos (Harvard Medical School, bacterial pathogenesis).

Sam Miller

His laboratory is focused on defining the molecular basis of bacterial pathogenesis and interactions with eukaryotic cells, with a special emphasis on innate immune response to Gram-negative bacteria. Some of Dr. Miller’s important contributions include: defining how Salmonella senses antimicrobial peptides and pH to promote pathogenesis, environmental regulation of Lipid A structure of Gram-negative bacteria to promote resistance to antimicrobial peptides and alter recognition by mammalian LPS receptor complex, definition of structure and function of type III secretion machinery and effector proteins, the definition of important genetic and functional adaptations of Pseudomonas aeruginosa infecting the airways of individuals with cystic fibrosis,  and recently, the development of technology to define human diversity in innate immune recognition of bacteria, and a development of a biosensor for c-di-GMP to visualize second messenger dynamics in living bacteria.
