Members Peter Cresswell, PhD Yale University New Haven, CT Dr. Peter Cresswell is the Eugene Higgins Professor of Immunobiology and Professor of Cell Biology and Dermatology at the Yale School of Medicine, and an investigator of the Howard Hughes Medical Institute. Dr. Cresswell has made many important contributions to immunology, including the discovery and identification of the MHC class II molecules, which immune cells use to display antigens and convey information about targets to each other, and viperin, a protein that plays important roles in response to viral infection. He is a fellow of the Royal Society, U.K., and has been elected to the National Academy of Sciences. His current work continues to focus on the mechanisms behind antigen processing that enable the adaptive immune system to carry out coordinated responses against intruders and infected cells.
