Dr Helen Walls BSc MPH(Hons) PhD

Assistant Professor

Background

I have an MSc(Hons) from the University of Auckland and a PhD in epidemiology from Monash University. After working at the Australian National University I obtained 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).

I have also worked in public health in New Zealand regionally and with the Ministry of Health, and with the World Health Organization (Geneva) on trade policy, diets and non-communicable disease.

I am an Associate Editor of the journal BMC Obesity.

Teaching

I am the Module Organiser of the MSc module 'Health Policy, Process and Power' (distance learning). I also lecture on the module 'Globalisation and Health' and supervise distance learning student projects for the MSc Global Health Policy.

Research

I am particularly interested in the structural drivers of public and global 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 (SOAS).
 
I am also involved with work examining decision-making processes in vaccination policy, and on trade in health services and patient mobility.
