Mary Norval

Mary is an emeritus professor at the University of Edinburgh, whose career focused on the impacts of UV radiation on human health, particularly in immunology. She started her career as a virologist in the 1970s, initially intrigued by skin infections like cold sores triggered by sunlight in herpes simplex virus cases. This curiosity led her to photo-immunology, a field studying how light influences immune functions, marking her transition from virology to immunology.

Throughout her career, Mary explored how UV radiation can suppress immune responses. This research holds significant implications for vaccination efficacy, especially considering that sunlight exposure might lower vaccine effectiveness—a crucial consideration for public health strategies globally.

Apart from the dangers, Mary also highlighted the benefits of UV exposure, like vitamin D synthesis, advocating for balanced sun exposure to harness these benefits without increasing skin cancer risks. Her notable scientific contributions include establishing the role of urocanic acid in immunosuppression and showing that UV radiation can modulate immune responses during microbial infections.

Mary is also remembered fondly by her students for her passionate and clear teaching style, which sparked lifelong interests in molecular biology. Even years after retirement, she continues to inspire and contribute to the academic community by engaging in research meetings and mentoring young scientists.
