Juliana Tolles, MD, MHS: My research interests include resuscitation, prehospital medicine, and adaptive clinical trial design.  I am a site investigator for the SIREN research network at Harbor-UCLA (https://siren.network/).  In the past few months, I have focused my efforts on COVID-19 surge modeling for the county of Los Angeles.  Pubmed Bibliography


Ross Fleischman, MD, MCR: As physician lead for emergency medicine for the electronic health record of the LA County department of Health Services, my interests include using large clinical datasets for research.  Seeing over 400,000 ED patients annually, the three emergency departments of the LA DHS share a single electronic health record and provide a wealth of data for researchers at Harbor-UCLA.  Recent projects include antibiotic and opioid stewardship interventions, national epidemiology of firearms injuries, pediatric appendicitis, and trauma epidemiology.

Kabir Yadav, MDCM, MS, MSHS: I am dual-boarded in Emergency Medicine and Clinical informatics, and have two Masters to match (Clinical Research Methods, and Translational Science). I am core faculty at the UCLA CTSI for both the Community Engaged Research Program, and Biomedical Informatics. I have been funded through NIH, CDC, PCORI, and foundations, most recently Co-PI for the Southwest SIREN Hub to perform nationwide emergency care clinical trials. I seek to leverage technology and implementation science to perform collaborative health services research focused on improving patient and provider decision making. I partner with community to do mutually meaningful research with an emphasis on social determinants of health. Pubmed Bibliography


Social EM Research Group: (Dennis Hsieh, MD, JD; Shamsher Samra MD, MPhil; Kabir Yadav, MD, MS, MSHS; Mohsen Saidinejad, MD, MBA; Adedamola Ogunniyi, MD; Kian Preston-Suni, MD, MPH) We collaborate on a number of projects on issues relating to social emergency medicine and the social determinants of health and work closely with Juliana Tolles, MD, MHS and Ross Fleischman, MD, MCR to develop research plans and evaluate these projects (see above). 


Tim Horeczko, MD, MSCR: My research interests include pediatric emergency medicine, study design, and translation of medical research via educational methods such as podcasting, FOAMed. Pubmed Bibliography

Amy H. Kaji MD, PhD: My research interests include methodology and study design, trauma, appendicitis, resuscitation, airway/intubation, and disaster/EMS. I was the emergency medicine PI for the PCORI multi-center study Comparing Outcomes of Drugs and Appendectomy (CODA), the site PI for the National Emergency Airway Registry (NEAR), and am currently the PI for a study investigating the use of a device that records compression measures, drug administration, etc.  I serve as a methodological and statistical editor for Annals of Emergency Medicine and JAMA Surgery and am a methodologist for the ACEP Clinical Policies Committee. Pubmed Bibliography


Mohsen Saidinejad, MD, MS, MBA: I currently serve as the Director for the Institute for Health Services and Outcomes Research at the Lundquist Institute for Biomedical Innovation at Harbor UCLA. My academic areas of focus include acute presentation of pediatric chronic diseases, technology use in ED aftercare, health policy, and emergency medical services for children.  I have had grant funding through foundations, CTSI, the NIH, and most recently from HRSA, and  I serve as a member of the executive core and one of three national leads for the knowledge management domain for the HRSA funded EMS for Children Innovation and Improvement Center program. (https://emscimprovement.center/).  I also serve as a member of the dissemination committee for the Pediatric Emergency Care Applied Research Network (PECARN) (https://www.pecarn.org/)  representing the EIIC.

Roger J. Lewis MD, PhD: My expertise centers on adaptive and Bayesian clinical trials, including platform trials; translational, clinical, health services and outcomes research; interim data analysis; data monitoring committees; and informed consent in emergency research studies. These clinical trial designs use the incoming stream of information that exists during the conduct of a clinical trial to trigger changes in key clinical trial characteristics to improve the ethical balance, statistical efficiency, or scientific value of the trial relative to a fixed, non-adaptive trial design. Pubmed Bibliography


Marianne Gausche-Hill MD: I am the Medical Director for Los Angeles County Emergency Medical Services (EMS) Agency, and my research interests include EMS, pre-hospital care of children, and pediatric emergency medicine. Key studies have included a study of pre-hospital airway management for children published in JAMA 2000 and the National Pediatric Readiness Project published in JAMA–Pediatrics in 2015.
