Who Dr Simon Williams is

Dr Simon Williams is a Lecturer in Psychology and public health researcher at Swansea University, and an Adjunct Assistant Professor in the Department of Medical Social Sciences at Northwestern University, Chicago. He also holds a consultancy role with the World Health Organisation. He completed his PhD in Sociology and Social Policy at Cardiff University, and has previously held positions at Aston University, the University of Bath and the University of Cambridge. He is known for his work on the health impacts of extreme heat, particularly the disproportionate risks faced by older adults, and has argued that such heatwave-related health consequences are emerging sooner and at lower levels of warming than previously understood. His broader public health research spans pandemic policy, COVID-19 health behaviours, and corporate influences on public health, and has been covered by outlets including the BBC, The Times, and Science Magazine.

What Dr Simon Williams has said

• “One thing we learned from Covid is how important it is that messages from health authorities and governments are clear and aligned. When people receive conflicting, unclear or mixed messages about health advice, such as when to wear masks, this can be confusing for people and can undermine the messages.”

• “The lack of new cases is a good sign and may signal that the Kent outbreak has been contained. However, we can't rule out [that] there are no further cases linked to this outbreak because the latency period, the time between exposure and symptom or disease alert, for MenB can sometimes be longer than a few days.”

• “This is a very significant study, with findings suggesting that heatwaves and extreme heat exposure is going to be a growing threat to human health in the coming years. In particular, it shows that heatwaves have unequal health impacts, with older adults particularly vulnerable.”
