Roitt’s Essential Immunology Peter J. Delves Professor Delves obtained his PhD from the University of London in 1986 and is a Professor of Immunology at UCL (University College London). His research has focused on molecular aspects of antigen recognition. He has authored and edited a number of immunology books, and teaches the subject at a broad range of levels. Seamus J. Martin Professor Martin received his PhD from Th e National University of Ireland in 1990 and trained as a post - doctoral fellow at University College London (with Ivan Roitt) and Th e La Jolla Institute for Allergy and Immunology, California, USA (with Doug Green). Since 1999, he is the holder of the Smurfi t Chair of Medical Genetics at Trinity College Dublin and is also a Science Foundation Ireland Principal Investigator. His research is focused on various aspects of programmed cell death (apoptosis) in the immune system and in cancer and he has received several awards for his work in this area. He has previously edited two books on apoptosis and was elected as a Member of Th e Royal Irish Academy in 2006 and as a member of Th e European Molecular Biology Organisation (EMBO) in 2009. Dennis R. Burton Professor Burton obtained his BA in Chemistry from the University of Oxford in 1974 and his PhD in Physical Biochemistry from the University of Lund in Sweden in 1978. After a period at the University of Sheffi eld, he moved to the Scripps Research Institute in La Jolla, California in 1989 where he is Professor of Immunology and Molecular Biology. His research interests include antibodies, antibody responses to pathogens and vaccine design, particularly in relation to HIV. Ivan M. Roitt Professor Roitt was born in 1927 and educated at King Edward ’ s School, Birmingham and Balliol College, Oxford. In 1956, together with Deborah Doniach and Peter Campbell, he made the classic discovery of thyroglobulin autoantibodies in Hashimoto ’ s thyroiditis which helped to open the whole concept of a relationship between autoimmunity and human disease. Th e work was extended to an intensive study of autoimmune phenomena in pernicious anaemia and primary biliary cirrhosis. In 1983 he was elected a Fellow of Th e Royal Society, and has been elected to Honorary Membership of the Royal College of Physicians and appointed Honorary Fellow of Th e Royal Society of Medicine.
