Dr. William Hay is Professor of Pediatrics and a faculty member of the Section of Neonatology at the University of Colorado Health Sciences Center. Dr. Hay received his BA degree from Dartmouth College and his MD from Yale University. He completed his residency in Pediatrics at the University of Colorado School of Medicine, where he also completed a fellowship in Neonatal-Perinatal Medicine and Research.

Dr. Hay has remained at the University of Colorado Health Sciences Center throughout his academic career. He served as Head of the Section of Neonatology for 10 years. Currently, he is Director of the Training Program in Neonatal-Perinatal Medicine and principal investigator of a NIH Training Grant in Perinatal Medicine and Biology. Dr. Hay also is Associate Director of the NIH-Department of Pediatrics General Clinical Research Center, as Director of the Neonatal CRC. Dr. Hay's basic research currently is supported by three NIH RO1 project grants to study various aspects of placental and fetal growth restriction, with specific attention to placental nutrient transfer and metabolism, fetal insulin secretion, and fetal insulin action. His clinical research through the CRC focuses on early postnatal intravenous nutrition of the extremely low birth weight infant, as well as pulse oximetry. Dr. Hay has served as a member of three NIH study sections over a 12-year period, and twice as chair of the NIH-CSR Human Embryology and Development-I Study Section.

Dr. Hay is Secretary-Treasurer of the American Pediatric Society. He travels widely, lecturing on fetal and neonatal nutrition and growth and serving as a visiting scientist and professor. He is senior editor of Current Pediatric Diagnosis and Treatment (published by Appleton & Lange), co-editor of NeoReviews (published by the American Academy of Pediatrics), and on the editorial boards or advisory boards of Pediatric Research, Reproduction Fertility and Development, Trophoblast Research, and the Placental Association of the Americas . 


Dr. Katsuyuki (Kats) Miyasaka is Director of the Department of Anesthesia and ICU at the National Children's Medical Center in Tokyo, Japan. He graduated from Shinshu University Medical School in Nagano, Japan in 1969. After internship and residency in Japan, he spent four and a half years in Canada and the United States. He was a clinical fellow in pediatric critical care at the Hospital for Sick Children in Toronto in 1973 and in pediatric anesthesia and ICU at the Children's Hospital of Philadelphia, University of Pennsylvania Medical School in 1974. He held a staff position in the pediatric ICU at HSC from 1975-1977, after which he returned to Japan as a staff anesthetist at the National Children's Hospital in Tokyo. He became director of the Pathophysiology Research Laboratory at the National Children's Medical Research Center in Tokyo in 1984, a position he held until 2001. He became Anesthetist-in-Chief of the Department of Anesthesia and ICU at the National Children's Hospital in Tokyo on 1988. He held this position through March, 2002, at which time the hospital was expanded into the National Children's Medical Center, the hospital affiliated with the National Center for Child Health and Development.  He was appointed as AW Conn Visiting Professor of Anaesthesia and Critical Care at the University of Toronto in 1999.

His main areas of interest in pediatrics include conventional ventilation, high frequency oscillation, non-invasive monitoring, cardiorespiratory physiology, critical and emergency care, pain management, telemedicine, home ventilatory care, and medical informatics. He has published extensively in both Japanese and international journals and has served on numerous editorial boards. He has co-authored several papers with Dr. Takuo Aoyagi, the inventor of pulse oximetry. He is also active in the promotion of continuing medical education in Japan.

While deeply involved in developing new technologies, Kats always places emphasis on meeting the needs of the patient first. His activities in research and medical care focus on improving the standard of care.

He received the Yamamura Award from the Japanese Society of Anesthesiologists and the Inoue Award from the National Science and Technology Agency in 1991 for his work on high frequency oscillation. He received a President's Citation from the Society of Critical Care Medicine in 2001 in recognition of his contribution to international exchange.
