个人简介
Dr John P. Ansah is an Assistant Professor of the Programme in Health Services and Systems Research, Duke-NUS Medical School and a faculty fellow at Residential College 4, National University of Singapore.
His recent work includes modelling the trajectory of the Covid-19 outbreak in Singapore, to understand how different interventions (such as containment, social distancing and attainment of herd immunity) may impact on the community spread of COVID-19 in Singapore. The study uses Susceptible-Exposed-Infectious-Recovered (SEIR) model to simulate the dynamics of COVID-19 infection, accounting for the impact of asymptomatic infections.
Asst Prof Ansah holds a PhD degree in Systems Science methodology of System Dynamics, and has 10 years’ experience in the application of simulation modelling to complex health policy issues. His research uses computational modelling—with systems thinking and System Dynamics methodology as the foundation—coupled with the active involvement of stakeholders to better understand complex health systems issues to inform policy and interventions to improve health outcomes. His research interests lie broadly in the area of health systems improvement—to address strategic and operational health and social care challenges – and the evaluation of health system-wide impacts of complex health and social care interventions. Current projects includes long-term care needs, resilience and hip fracture recovery trajectories among the elderly, patients flow in the emergency department, enhanced primary care for an ageing society and human resources for health.
