Pediatric Hospitalist, Barbara Bush Children’s Hospital 

Medical Director of the Hannaford Simulation Center at Maine Medical Center

What are your research interests? What is the most innovative sim-related activity you do in your work?

My favorite pediatric simulation activity is weekly interprofessional inpatient pediatric team training, where my research team studies factors influencing engagement during debriefing. I am also proud of systems integration work at our sim center, including high fidelity simulation-based testing the simultaneous landing of two helicopters prior to the opening of MMC’s new helipad last January, as well as our team’s facilitation of just-in-time COVID related efforts around intubation, code blue response, OR protocols, patient transport, and telemedicine.

Why did you join IPSS?  What do you gain from your IPSS membership?

I am grateful for the collaboration and networking opportunities available within IPSS, and from those she has developed research interests in Simulation-Based Assessment of Competency and Interprofessional Debriefing.

What did you appreciate most at IPSSV?

I especially enjoyed hearing about the creative adaptation by simulationists around the world to the challenge presented by the COVID pandemic.

Dr. Leah Mallory is a Pediatric Hospitalist at the Barbara Bush Children’s Hospital and the Medical Director of the Hannaford Simulation Center at Maine Medical Center.  Dr. Mallory attended Stanford University School of Medicine and completed her Pediatric Training in the Boston Combined Residency Program, where she also served as chief resident.


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.
