Dr Sarah Ryan has been made patron of disability campaign group My Life My Choice.
Dr Ryan became a well known champion of disability rights after her 18-year-old son Connor, who had epilepsy, autism and a learning disability, drowned in a bath at Slade House in Headington in 2013.
The Oxford University researcher, who specialises in learning disability research, accepted the figurehead position at the invitation of the Oxford-based charity’s trustees.
