Steven J. Jonas, MD, PhD

Pediatric Hematology Oncology


Dr. Jonas is a UCLA physician-scientist specializing in Pediatric Hematology/Oncology. He received a bachelor's degree in materials science & engineering and a master's degree in biomedical engineering prior to starting his medical training to pursue his M.D. and his Ph.D. degrees at UCLA through its NIH-supported Medical Scientist Training Program. Dr. Jonas completed his pediatric residency and fellowship training in pediatric hematology/oncology at UCLA Mattel Children's Hospital where he was the first trainee in a specialized physician-scientist track established by the Department of Pediatrics at the UCLA David Geffen School of Medicine.

He leads a multidisciplinary research team that targets the development and application of new nanotechnologies and methods to support the childhood cancer and regenerative medicine research communities in accelerating the discovery and implementation of innovative gene therapy approaches and diagnostic strategies. His research is primarily focused on the design of nanotechnologies that enable rapid, safe, cost-effective, and efficient delivery of genes and genome-editing machinery to immune and stem cells for manufacturing new gene and cellular therapies.

In 2019, Dr. Jonas received the prestigious Director's Early Independence Award from the National Institutes of Health. He is a member of the California NanoSystems Institute, the UCLA Eli & Edythe Broad Center of Regenerative Medicine & Stem Cell Research, and the Jonsson Comprehensive Cancer Center and is a Young Investigator awardee of the Alex's Lemonade Stand Foundation for Childhood Cancer Research, the Hyundai Hope on Wheels Foundation, and the Tower Cancer Research Foundation.
