Helen Johnson

Helen Johnson is a Research Fellow at LSE Health, London School of Economics and Political Science, specializing in AI applications for political decision-making and pandemic policy. Previously, she served as a mathematical modeller at the European Centre for Disease Prevention and Control (ECDC) in Stockholm and the European Commission in Brussels from 2017 to 2023, advising on social distancing measures, border closures, pharmaceutical procurement, and vaccine strategy during critical public health emergencies.

Her academic credentials include:

• Degrees in Physics and Biomolecular Science from Imperial College London
• Degree in the Control of Infectious Diseases from the London School of Hygiene & Tropical Medicine

Dr. Johnson's research centers on leveraging Artificial Intelligence to address uncertainty and bias in policy formulation, with expertise in causal inference, complex systems, and infectious disease dynamics. She advances Bayesian methodologies for health outcome analysis and actively promotes understanding of non-linear dynamics and dynamic systems in governance contexts—emphasizing how historical patterns fail to predict future crises and how interventions may trigger unintended consequences. Her work bridges advanced mathematical modeling with actionable public health strategy.
