Ran Barzilay, MD PhD, is an Assistant Professor of Psychiatry at Penn Medicine. Dr. Barzilay is a child and adolescent psychiatrist with background in translational neuroscience ranging from basic molecular neuroscience to clinical studies. He studies mechanisms that drive variability in development of youth growing up under environmental stress (exposome). His research integrates multimodal data in attempt to dissect the interplay of biological and environmental factors that explain patients' susceptibility versus resilience.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
