Wakenda K. Tyler, MD, MPH specializes in the treatment of benign and malignant tumors of the bones and soft tissues in patients of all ages. As a musculoskeletal oncologist, Dr. Wakenda K. Tyler, MD, MPH specializes in the treatment of benign and malignant tumors of the bones and soft tissues in patients of all ages. As a musculoskeletal oncologist, Dr. Tylers practice is focused on the non-operative and operative management of primary soft tissue and bone cancers, sarcomas, and metastatic bone cancer. Dr. Tylers goal is to provide compassionate surgical care that achieves cure of cancer whenever possible by leveraging the latest advances in non-operative management, minimally invasive, and reconstructive surgical techniques. When cure is not possible she strives to achieve pain control and improve function as best as possible for every patient.Dr. Tyler earned her medical degree from The John Hopkins University School of Medicine, where she also received a masters degree in public health. She went on to complete residency training in orthopedic surgery at the Hospital for Special Surgery, followed by a fellowship in musculoskeletal oncology at the Memorial Sloan Kettering Cancer Center.As an active physician scientist, Dr. Tylers research interests overlap with her clinical practice and center around the treatment of patients with bone and soft tissue tumors and conditions that lead to osteolysis (bone destruction as a result of implant wear and loosening or presence of a tumor). She has written medical journal articles on several bone diseases, the effectiveness of medication in penetrating to the site of bone grafts, and the strength of the bone and prosthesis union.

Rakesh Sahni, MBBS, is Professor of Pediatrics at Columbia University Medical Center, Medical Director of the Neonatal Intensive Care Unit at NewYork-Presbyterian/Morgan Stanley Children’s Hospital, and Director of the Infant Physiology Laboratory at Columbia University’s College of Physicians and Surgeons. After earning his medical degree from Maulana Azad Medical College, University of Delhi in India, Dr. Sahni did pediatric residency training in India, the United Kingdom, and the United States. He further completed fellowship training in neonatal-perinatal medicine at Columbia University in 1993 and has been a faculty member since then. Dr. Sahni’s major area of interest is neonatal physiology and behavior. His research goals are to understand the physiological basis of various processes during the neonatal period. He Investigates how these processes alter cardiorespiratory activity, thermal regulation, and neurobehavioral organization in the early developmental stages of infants with very low birthweights. He also studies the acute physiological effects of interventions in these infants, such as nutrition and postural alteration, as well as the long-term effects of early nutritional experiences, with emphasis on cardiovascular, metabolic, and cognitive alterations at the resting level and stimulus responsiveness of the maturing sympathetic nervous system. In addition, Dr. Sahni collaborates with researchers from the Department of Developmental Neuroscience to study the interactive relationships among body position during sleep, body temperature, and cardiorespiratory and neuroelectric activity in the regulation of heart functions during early development of low birthweight infants. His long-term objectives are to explain the body’s vulnerabilities underlying sudden infant death syndrome (SIDS) and to develop age-appropriate, noninvasive tests to identify infants at greatest risk for SIDS. His research interests also include continuous invasive and noninvasive physiological monitoring during neonatal intensive care in preterm and term infants. He has published more than 75 original papers and more than 95 abstracts, and is a recipient of several grant awards.
