Jeffrey S. Barrett, PhD, FCP Areas of Expertise: Pharmacokinetics, pharmacodynamics, clinical trial simulation, biomarkers Appointments and Referrals: 1-800-TRY-CHOP (1-800-879-2467) Background Dr. Barrett’s current efforts in conjunction with the mission of the Clinical Pharmacology and Therapeutics Division are focused on the investigation of sources of variation in pediatric pharmacokinetics and pharmacodynamics. Applied clinical pharmacologic investigation coupled with modeling and simulation strategies are pursued with the intention of developing rational dosing guidance in various pediatric populations for both marketed and exploratory compounds. Clinical trial simulation is to be utilized prospectively to explore design dependencies and parameter sensitivities. Dr. Barrett also directs the Laboratory for Applied PK/PD which is focused on the development of pharmacometric approaches to advance PK/PD, novel biomarker development and disease progression modeling. Education and Training Additional TrainingPhD, Pharmacokinetics, University of Michigan Titles and Academic Titles Research Associate Professor 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.
