Silke Rickert-Sperling, MD, is Professor of Cardiovascular Genetics at the Charité, Medical University Berlin and coopted professor at the Faculty of Biology, Chemistry and Pharmacy of the Free University Berlin. She leads an interdisciplinary research group at the ECRC (Cardiovascular Genetics Group). Her research focuses on elucidating the molecular mechanisms as well as genetic parameters underlying cardiac development in health and disease. She hopes to combine knowledge of molecular etiologies and mechanisms to eventually improve preventive and therapeutic opportunities for patients. Robert Kelly, PhD, is Group Leader at the Developmental Biology Institute of Marseilles - Luminy in France. His groups´ research focuses on the cellular and molecular processes regulating development of these progenitor cells in the mouse and their contribution to the developing heart and craniofacial skeletal muscles.Dr Driscoll is Professor of Pediatrics, Mayo Clinic College of Medicine and the Mayo Clinic, Rochester, Minnesota, USA. He is emeritus chair of the Division of Pediatric Cardiology, Mayo Clinic. Dr Driscoll was chair of the Committee on Cardiovascular Diseases of the Young of the American Heart Association. He served as chair and editor of the sub-board of Pediatric Cardiology of the American Board of Pediatrics. He co-edited the 6th, 7th, and 8th editions of Moss and Adams' "Heart Disease in Infants, Children, and Adolescents". He authored the textbooks "Fundamentals of Pediatric Cardiology" and "Interpretation of Intracardiac Electrograms". In addition, he has published over 200 peer review manuscripts covering a wide variety of cardiac issues.
