Zoonoses and One Health
Immunisation and vaccine preventable diseases
Health effects of household crowding, healthy housing
Rheumatic fever, skin infections, chronic effects of infectious diseases
Seasonality of disease, health effects of climate change, e.g. on infectious diseases
Environmental health, drinking water quality, water pollutants, e.g. nitrates
Drug law reform and harm minimisation, e.g. needle exchange programme
Public health services organisation and capacity, e.g. surveillance and outbreak investigation
Global health security, e.g. the International Health Regulations ( IHR 2005)
Michael has a strong interest in science communication. In 2023 he launched the Public Health Communications Centre where he is its inaugural director.
Michael has worked in a range of roles, including being a medical advisor to a Minister of Health, for regional public health services, at a Crown Research Institute ( ESR ), and for the World Health Organisation in Manila and Geneva. His current positions include:
