Dr Alexandra Kalbus

Assistant Professor

United Kingdom

I am an Assistant professor in the Department of Public Health, Environments and Society. I am a public health researcher using quantitative methods to understand key drivers of population-level diets and how policies can be employed to improve dietary health in the UK. I hold a PhD in public health from LSHTM, which examined the relationship between the neighbourhood food environment and food and drink purchasing in England, and how this relationship changed during the COVID-19 pandemic. Before the PhD, I completed an undergraduate and master's degree in Health Sciences, which equipped me with skills across multiple disciplines, including epidemiology, health economics, medicine, statistics, ethics, public health, occupational health and health promotion. I am currently involved in a UKRI-funded project examining the links between price changes linked to climate shocks and dietary quality in the UK. Previously, I have been part of an NIHR SPHR-funded evaluation of the calorie labelling regulations implemented in England in April 2022.

Teaching

I am a seminar leader for the MSc modules 'Bastic Statistics for Public Health and Policy' and 'Evaluation of Public Health Interventions'. I also supervise MSc summer projects.

Research

I am broadly interested in the structural determinants of population-level health and health inequalities and how policy interventions can improve health and reduce inequalities. An epidemiologist by training, I mainly use quantitative methods in my research. I have a strong background in public health nutrition in the UK, including neighbourhood-level exposure to the food environment both in the physical and online environment, impact evaluation of food policy, and economic drivers of food purchasing.
