Dr Anna Hansell, Assistant Director of SAHSU

Job Title and Responsibilities:
Job Title: Assistant Director Small Area Health Statistics Unit
Clinical Reader in Environmental Epidemiology

As Assistant Director of SAHSU, I lead on and support infrastructure for >20 SAHSU studies examining long-term health effects of environmental exposures and developing new methods in using routine (administrative) data. I have oversight of the SAHSU databases containing over 300 million patient records. I hold an honorary consultant contract with Imperial College Healthcare NHS Trust. I also teach and chair the Imperial Masters in Public Health exam board.

Main research projects:

• Waste management - Incinerators Study and bioaerosols from waste composting
• Long term health effects of noise and health (several projects)
• Long term health effects of air pollution (several projects)
• Rapid Inquiry Facility
• Small area statistical methods development

About Me:
My background is in internal (hospital) medicine, following which I trained in public health then environmental epidemiology. I am currently a Reader in Environmental Epidemiology at Imperial College London, My special research interests are in environmental noise and air pollution, respiratory disease epidemiology and use of small area data. I have conducted a number of projects looking at health effects of very long term (20-40+ years) and lifetime air pollution exposures. I currently am one of few epidemiologists in the UK currently researching environmental noise and health. I have published on health effects of aircraft and road traffic noise on mortality, cardiovascular disease and birth outcomes using both SAHSU and cohort data working in the UK and with European partners in e.g. in the EU-funded European Network on Noise and Health (ENNAH) and HYENA (Hypertension and Exposure to Noise near Airports) study.
