The Center for Platelet Research Studies (CPRS) is an internationally recognized, multidisciplinary center for the study of platelets by state-of-the-art methods. The CPRS is an integrated research group that performs basic bench research, translational research, and clinical research on platelets and related aspects of hemostasis and thrombosis.
Research Background
Dr. Alan D. Michelson is Professor of Pediatrics and Medicine, Emeritus at Harvard Medical School. He is the Director Emeritus of the Center for Platelet Research Studies and the former Director of the Thrombosis and Anticoagulation Program at Dana-Farber/Boston Children's Cancer and Blood Disorders Center.
Dr. Michelson is the editor of the textbook Platelets (Elsevier/Academic Press), which integrates the entire field of platelet biology, pathophysiology and clinical medicine into a comprehensive source of knowledge about platelets for clinicians, pathologists, and scientists. The first edition of Platelets, published in 2002, was the winner of the Best Book in Medical Science award from the Association of American Publishers and was called “landmark” by the New England Journal of Medicine. The third edition of Platelets, published in 2013, was the winner of the Highly Commended Prize in the category of Internal Medicine, British Medical Association (BMA) Medical Book Awards. The 67-chapter, 1268-page fourth edition of Platelets was published in 2019 and has been translated into Chinese.
Dr. Michelson received the 1st Annual Esteemed Career Award from the International Society on Thrombosis and Haemostasis (ISTH) in 2019. He is a past Chairman of the Platelet Physiology Scientific Subcommittee of the ISTH. Dr. Michelson has been an invited participant in numerous National Institutes of Health working groups, international workshops and consensus conferences. Since 2006 he has been the co-organizer and co-chair of the biennial International Platelets Symposium.
Dr. Michelson has published more than 500 original research articles, invited reviews and original research abstracts. His publications have been cited over 20,000 times in the medical and scientific literature. Dr. Michelson has been the principal investigator on more than 100 research grants. He has been an invited speaker at over 200 major medical conferences worldwide. Dr. Michelson is an inventor on two awarded and three provisional U.S. patents. He has been a consultant and served on scientific advisory boards for numerous biotechnology and pharmaceutical companies.
After receiving his medical degree with honors from the University of Adelaide, Australia in 1974, Dr. Michelson continued his medical and research training on a Fulbright Scholarship at Boston Children’s Hospital, Brigham and Women’s Hospital, and Harvard Medical School. Dr. Michelson was awarded an honorary Master of Arts degree by Harvard University in 2010.
