Summary

In this public lecture, physicist Catherine Beauchemin discusses the erosion of public trust in health research and how physics-based approaches can help. She begins by outlining the scientific method and its reliance on falsifiability, skepticism, and independent verification. She then highlights problems in health research, such as non-reproducible studies, publication bias, and the influence of financial interests, using examples like the hydroxychloroquine controversy and retracted papers. Beauchemin contrasts the mathematical rigor of physics with the often qualitative nature of biology, arguing that mathematical modeling can provide deeper insights into viral dynamics. She presents her own work on influenza, showing how mathematical models can extract parameters like eclipse phase and virus production rate from experimental data. The lecture concludes with a discussion of COVID-19 modeling and the importance of transparency and data sharing. Throughout, she emphasizes the need for a more quantitative approach in virology to improve understanding and public trust.
