About Betsy Hunt

Elizabeth A. Hunt, MD, MPH, PhD, “Betsy”, is the David S. and Marilyn M. Zamierowski Director of the Johns Hopkins Medicine Simulation Center. She graduated as a member of the Alpha Omega Alpha Honor Society from Albany Medical College in 1995. This was followed by a combined residency in Internal Medicine and Pediatrics, and a Pediatric Chief Residency at Duke University. Subsequently, she did a Pediatric Critical Care fellowship at Johns Hopkins. Dr. Hunt was elected to the Delta Omega Honor Society at the Johns Hopkins Bloomberg School of Public Health where completed a Masters in Public Health and a PhD in Clinical Epidemiology. Her thesis involved the use of simulation to assess the performance of pediatric residents during pediatric cardiopulmonary arrests.

She is currently an attending pediatric Intensivist in the Johns Hopkins Pediatric Intensive Care Unit, and an Associate Professor in the Departments of Anesthesiology & Critical Care Medicine and Pediatrics and is Chair of the Johns Hopkins CPR Advisory Committee. She is a founding member and Senior Co-Chair of INSPIRE, i.e. International Network of Simulation-based Innovation, Research and Education. Dr. Hunt’s academic efforts are dedicated to exploring innovative methods to improve the quality of care delivered and ultimately clinical outcomes for children who suffer a cardiopulmonary arrest. This includes implementation of Rapid Response Systems, cardiac arrest data capture and debriefing, medical device and simulator redesign and the introduction of novel simulation educational approaches including data driven debriefing and introduction of the approach “Rapid Cycle Deliberate Practice.” Dr. Hunt has been fortunate to have the opportunity to present, practice or teach about pediatric resuscitation issues throughout the world.


I am a UK-trained Neonatologist working in Starship NICU in Auckland, New Zealand. I am a member of the Douglas Starship Simulation faculty and lead the simulation programmer in NICU. My key simulation interests include education, communication and patient safety. I have been an active member of IPSS since 2011, member of the Education Committee since 2012, am a past Co-Chair of the Education Committee (2017-2018) and a current member of the Board of Directors. In collaboration with others, I established the IPSS-INSPIRE Fellowship in 2018 and am on the working group leading this initiative. My vision for IPSS is to continue to support collaborative knowledge sharing and research development in the pediatric and perinatal simulation community. My wish for IPSS is to see an increasing number of non-physician members and to support and develop the ability of those still at the early stage of simulation.



Dr. Carl Horsley

Intensivist, Counties Manukau Health, Auckland, New Zealand

Clinical Lead for Patient Safety, Health Quality and Safety Commission, New Zealand

Dr. Carl Horsley dual trained in Emergency Medicine and Intensive Care, and works clinically in the Critical Care Complex of Middlemore Hospital in Auckland, New Zealand. As part of his work there, he developed an in-situ simulation program specifically focused on building the adaptive capacity of the ICU team. This was put to the test in the Whakaari volcanic eruption with Middlemore being the national burns centre responding to a mass casualty event.

Carl is currently completing an MSc in Human Factors and System Safety at Lund University, Sweden with a thesis focusing on the sociology of safety.  He is also part of the Resilient Healthcare Society which is an international collaboration exploring the implications of resilience engineering in healthcare. As Clinical Lead for Patient Safety at the Health Quality Safety Commission, Carl is also involved in developing innovative approaches that support “work-as-done” by frontline to improve both patient care and staff wellbeing. He has published several book chapters on resilient healthcare and presented widely on the topic.


Dr. Andrew Petrosoniak

Emergency Physician & Trauma Team Leader, Assistant Professor

St. Michael’s Hospital and University of Toronto

Following an unsuccessful career as an intramural basketball player, Dr. Petrosoniak now works as an emergency physician and trauma team leader at St. Michael’s Hospital. He’s an assistant professor at the University of Toronto and an associate scientist at the Li Ka Shing Knowledge Institute. He’s the lead for translational simulation at St. Michael’s Hospital which involves the application of simulation techniques to identify issues and support the design of solutions related to healthcare delivery and improving health service outcomes.

More accurately, he seeks to reduce the number of F-bombs by providers linked to poor system/space design in healthcare. He also applies this work in the private sector as the co-founder of Advanced Performance Healthcare Design, a design and consulting firm that uses multi-modal simulation techniques to inform the design of clinical infrastructure, equipment and high performing teams.
