Dr Helen Walls
BSc MPH(Hons) PhD
15-17 Tavistock Place
My background includes a MSc(Hons) from the University of Auckland and a PhD in epidemiology from Monash University. After working at the Australian National University I was awarded an NHMRC Sidney Sax Public Health Fellowship and began working in 2012 with the School. Since this time I have also been affiliated with the Leverhulme Centre for Integrative Research on Agriculture and Health (LCIRAH).
Prior to my PhD studies, I worked in public health in New Zealand regionally and with the Ministry of Health. I have also worked with the World Health Organization (Geneva) on trade policy, diets and non-communicable disease.
I am an Associate Editor of the journal BMC Obesity. I am also an Honorary Senior Fellow at the University of Melbourne and a Research Associate at the University of the Witwatersrand.
I am Module Organiser for PHM109 'Health Policy, Process and Power' on the distance learning MSc in Public Health. I also lecture on the module 'Globalisation and Health' and supervise distance learning student projects for the MSc Global Health Policy.
I currently co-supervise PhD students, and welcome applications from current MSc students to supervise summer projects on food systems and policy and other areas related to my research interests.
I am particularly interested in the structural drivers of population health. Much of this work relates to food systems and nutrition, particularly the role of trade and agricultural policy in shaping nutrition and health, and governance responses.
I currently lead a programme of work funded by the Drivers of Food Choice Competitive Grants Program (Bill and Melinda Gates Foundation; UK Department for International Development) examining the impact of Malawi's agricultural input subsidy programme on food choice and dietary diversity. This is in collaboration with colleagues at the University of Malawi and the School of Oriental & African Studies.
I am also involved in work examining the use of evidence to inform health policy making, and trade in health services and migration.
