Director, Heart Institute Data Analytics and Research Program
Mark Abcede, M.B.A., CCRP
Mark has rejoined the Heart Institute after serving as a a clinical site manager of global research operations at PAREXEL. During his tenure at the Heart Institute from 2012 to 2016, Mark played a key role in the Heart Institute Research Committee, which he helped establish to ensure that the appropriate infrastructure existed to support the research endeavors of faculty, staff, external sponsors and donors. Additionally, he was instrumental in fostering collaborations between the Heart Institute and the UC San Diego Cardiac Mechanics Group, the Pediatric Heart Transplant Study, the Congenital Heart Surgeons’ Society and the Pediatric Heart Network. Mark earned his Bachelor of Arts in biology and chemistry at the University of San Diego and his Master of Business Administration (with an emphasis in healthcare management) at the University of Phoenix. He is currently completing a professional certificate program through UC San Diego in clinical trials design and management.

Director, 3D Innovations Lab (3DI Lab); Research Scientist
Justin Ryan, Ph.D.
Justin is bringing the art of 3D anatomical modeling — a highly technical and rapidly evolving field that holds incredible potential for transforming care — to Rady Children’s. A computer imaging and animation master-turned-biomedical engineer, Dr. Ryan joins us as director of the new 3D Innovations Lab (3DI Lab). The first of its kind in Southern California, the 3DI Lab will create 3D models and prints based on medical images, such as CT scans and MRIs, to support precise surgical planning and improve outcomes specifically for pediatric patients. In addition, the lab will train current and future physicians and scientists, develop educational resources for patients and families, and fuel further innovation in the 3D modeling space. An accomplished leader in his field, Dr. Ryan previously ran the Cardiac 3D Print Lab at Phoenix Children’s Hospital, where he created more than 500 unique cardiac models. The 3DI Lab and its services are a hospital-wide initiative — the lab’s unique interdisciplinary structure will open the benefits of 3D modeling to patients facing everything from spinal conditions to neurological disease to plastic surgery. For inquiries, please contact 3DPrintLab@rchsd.org.
