Autism is a condition that affects a person’s ability to interact socially and relate to the world around them. The degree to which a person is affected ranges across a wide spectrum, from severe difficulties in communicating to mild symptoms. Mia Langguth, a researcher at QBI, works part-time as a carer for Chris, a 24-year-old man with autism. She became a disability support worker almost by chance, but it's a job that has shaped the direction of her career.
