Ailsa J. Hall

Ailsa Jane Hall is a British biologist who is the director of the Sea Mammal Research Unit at the University of St Andrews. Her research considers the impact of contaminants on the risk of mortality in marine mammals.

Early life and education In 1985, Hall joined the University of Birmingham Institute of Occupational Health. Her early research considered the microbial health risks of post mortem workers. This work, which informed the Code of Practise for the Department of Health and Social Care, formed the basis of her doctoral research. She investigated an outbreak of phocine distemper amongst harbour seals. She moved to the University of St Andrews in 1996, where she worked on the immune response of seals. Whilst PCBs were banned in the late 1970s due to toxicity, they continue to be in circulation, and are able to resist extreme heat.

Hall investigates the impact of pathogens and contaminants on the health of marine mammals. She is interested in how contaminants and pathogens impact the early survival of animals. Hall focused her efforts on improving biodiversity in the ocean. She studied the impact of climate change on populations of humpback whales, showing a significant drop in breeding successes in the wild.

Hall was appointed Officer of the Order of the British Empire (OBE) in the 2022 New Year Honours for services to environmental protection and epidemiology.
