Bethan Peach Professor Bethan Lang’s PhD research looked at brain and muscle proteins, including acetylcholine (ACh) receptors. Prior to her retirement, she was a member of the myasthenia research team whose research determined that Lambert-Eaton myasthenic syndrome (LEMS) was also caused by antibodies. This led to the use of steroids and other immunosuppressant drugs and to a much improved diagnostic blood test. As well as being a trustee of myaware, Bethan is also on the scientific steering committee of the Dancing Eye Syndrome Support Trust. She is a keen Welsh rugby and QPR supporter and is married with two daughters.
