Overview

Tamara D. Simon, MD, MSPH, is a pediatric hospitalist with a research focus on improving the quality of evidence in inpatient health care provided to children with medical complexity. Since April 2020, Dr. Simon has held numerous leadership positions including faculty in the Division of Hospital Medicine in the Department of Pediatrics at the Keck School of Medicine of USC; member of the hospital medicine team at Children’s Hospital Los Angeles; principal investigator at The Saban Research Institute of Children’s Hospital Los Angeles (TSRI); CHLA Site Principal Investigator, Southern California Clinical and Translational Science Institute (SC CTSI).

Her research portfolio includes a clinical research focus is on cerebrospinal fluid (CSF) shunt infections and re-infections in children with hydrocephalus, a translational line of inquiry focused on the microbial environment of CSF shunt infections; and a health service research focus on improving the quality of care provided to children with medical complexity in the inpatient setting.

Dr. Simon is passionate about the mentorship she provides to residents, fellows and junior faculty with specific research interests in hospital medicine and other generalist fields, specifically those interested in the physician-scientist career path in this growing field. Dr. Simon parlayed her passion for mentorship into a leadership role as Faculty Director for Training, Education, Career Planning and Development and Associate Director for Training and Education within The Saban Research Institute at CHLA from 2020 to 2022. She was instrumental in refining existing programs and developing new programs that promote the conduct of high-quality research.

The support and guidance provided by Dr. Simon will continue to be a priority as she has been appointed to serve as the CHLA Site Principal Investigator, Southern California Clinical and Translational Science Institute (SC CTSI) effective June 2022. As the Site Principal Investigator Dr. Simon will provide operational and strategic leadership and direction for the SC CTSI, representing and advocating for the clinical and translational research interests and needs of CHLA investigators. As CHLA Site Principal Investigator, Dr. Simon will interface with CHLA leadership and research investigators to promote SC CTSI’s goal to be a leader in clinical and to translational research to benefit diverse communities benefit diverse communities and special populations.

A member of the editorial board of Hospital Pediatrics since 2010, Dr. Simon has been an Associate Editor since 2014. Dr. Simon also serves as a grant reviewer for the National Institutes of Health and various foundations.
