Emergency medicine physician, public health specialist, and digital health leader. Three decades building the systems that respond when every second counts — from prehospital emergency care to AI-enabled healthcare.
Dr Ng Yih Yng designs and scales the innovations that change how healthcare is delivered — combining human-centred design with digital health and AI to move ideas from pilot to national practice, and from national practice to measurable, everyday impact.
Dr Ng Yih Yng works at the crossroads where emergency medical services and public health meet digital health transformation. He is an associate professor at Saw Swee Hock School of Public Health at the National University of Singapore and an adjunct at the Prehospital Emergency Research Centre, Duke-NUS.
Over three decades, he has built extensive government service experience across multiple agencies — the Ministry of Defence, the Ministry of Home Affairs, and 11 years as a Visiting Consultant with the Ministry of Health's Hospital Services Division — while working directly within the healthcare system to manage emergency services, drive innovation, and lead digital health transformation.
He served as a Medical Officer with the Singapore Armed Forces from 1993 to 2018, including as Chief Medical Officer of the Singapore Civil Defence Force (2012–2018), where he led the transformation of Singapore's national EMS system — including the 995 emergency call centre, the R-AEDi AED registry (developed with the Singapore Heart Foundation), the HDB Save a Life residential AED programme, and the blueprint for digitalising the 995 ambulance fleet through the OMNII connected prehospital electronic medical record system. He was also the architect behind myResponder — Asia's first smartphone app to crowdsource bystander CPR and AED response for out-of-hospital cardiac arrest, now used by tens of thousands of registered community first responders across Singapore.
His health policy development experience spans the Ministry of Defence, the Ministry of Home Affairs — where he was HomeTeam Chief Medical Officer from 2015 to 2023 — and 11 years as a Visiting Consultant with the Ministry of Health's Hospital Services Division. From 2018 to 2025 he led digital health and AI innovation across the National Healthcare Group, as Director of the Digital and Smart Health Office and Director of the Health Empowered by AI Launchpad, driving NHG's "Hospital Without Walls" strategy and its cluster-wide AI adoption agenda.
Alongside these system-level roles, he has practised as a consultant emergency physician at Singapore General Hospital and Tan Tock Seng Hospital — work recognised with national honours including the Public Service Administration Medal (Silver) and the COVID-19 Resilience Medal.

"Yih Yng was an invited speaker for NCSS Social Service Summit 2025 speaking about innovation and digitalization. His sharing was inspirational yet simple and was able to connect with the audience — not with fanciful and complex concepts but inspiring people to innovate through rethinking existing concepts. It was truly an eye opener on how he was able to share his experiences to inspire the social service community to innovate. For those of us who have heard him speak, we indeed were very blessed! Highly recommended speaker!"

"As Head, Preventive Medicine Branch in HQMC, YY was an extremely strategic leader in responding to the rapidly changing information environment during the immediate post-SARS period in Singapore, as evidenced through his thoughtful and decisive deliberations in designing preventive protocols against future events. He further displayed strong and effective leadership in mobilizing the PrevMed officers and staff throughout this challenging period and successfully managed the operational demands of handling this severe emerging infectious disease."

"LTC Ng is one of the most helpful and collaborative people I've worked with. In a large, complex organisation, it is often challenging to obtain precise and accurate information that achieves work objectives in a timely manner. YY was always there to help. He sees the bigger organisational picture. He has no airs. An asset to any organisation!"
