My research interests include medical simulation, systems integration, patient safety and pediatric resuscitation. In addition, I am interested in investigating procedural care and simulation-based training. I have been funded for multiple clinical trials on a national level as a primary investigator and a co-investigator.

With my research, my team and I are attempting to find ways to strengthen airway management and team-based healthcare services for severely ill and/or injured children.

Along with these projects, I’ve assisted with study sections for the Agency for Healthcare Research and Quality and the National Institutes of Health (NIH). I have also reviewed several peer-reviewed journals.

I engaged in this kind of research because I am an educator at heart and enjoy the trials and challenges of caring for critically ill or injured pediatric patients. I was inspired to pursue medical training and work with children after seeing many great examples of superb physicians caring for patients and advancing medicine. This experience specifically included my advisor in medical school and one from my residency training, who are both pediatric emergency medicine physicians.

Over the years, I have been presented with teaching awards from the Cincinnati Children’s Hospital Medical Center, University of Cincinnati and external institutions. In 2015, I received an Educational Achievement Award from the Department of Pediatrics at Cincinnati Children’s Hospital.

I have more than 15 years’ experience in emergency medicine and I pursued a fellowship at Cincinnati Children’s Hospital in 2004. My research has been published in various respected journals, including Simulation in Healthcare: Journal of the society for simulation in healthcare, Journal of Neurosurgery: Pediatrics, Hospital Pediatrics and Academic Emergency Medicine.
