Alison read law at Oxford and Cambridge Universities. She advises clients on a wide range of pharmaceutical and health care matters and in litigation under the Consumer Protection Act 1987 involving general consumer products. She acted for the defendant in the successful case of Relph v Yamaha, the first case in the UK under the Consumer Protection Act.

Alison has been instructed by defendants in multi-party pharmaceutical and health care product liability litigation, including the coordination of the Hepatitis C group litigation for the National Health Service in A & Others v National Blood Authority. This involved the first substantive examination of the European Product Liability Directive. 

She has been involved in high profile trans-national litigation including acting on behalf of Rio Tinto plc in the House of Lords case of Connelly. Alison has also acted in complex scientific, technical and medical claims where defendant companies have faced not only legal challenges such as jurisdiction and limitation, as in the case of Brooks & Others v The Boots Company PLC, but also allegations of injury from sources as diverse as vaccines to radiation exposure.

She regularly contributes articles and lectures on product liability law.
