The Power List 2015
A pathologist for over 50 years, Peter’s focus of study is the acute inflammatory response – how it’s initiated, how it progresses, and its outcomes. This interest began in his early years as a pathologist, when he discovered during a postdoctoral fellowship that a fragment of complement component 5 is chemotactic for neutrophils, and has continued to this day as he attempts to identify tissue-damaging inflammatory products. According to a nominator, “his work in the field of sepsis and innate immunity has transformed scientists’ understanding of the disorder and the working of the immune system.” Peter spent two years serving as chief of the Immunology Branch of the Armed Forces Institute of Pathology before chairing the Department of Pathology at the University of Connecticut Health Center for nine years and at the University of Michigan for 25. He is now Godfrey D. Stobbe Professor of Pathology at the University of Michigan School of Medicine.
