Dr Sam Gandy is a Professor of Neurology and Psychiatry at the Icahn School of Medicine at Mount Sinai in New York City. He is an international expert in the metabolism of the sticky substance called amyloid that clogs the brain in people living with Alzheimer’s disease. In 2009, GQ magazine featured Prof Gandy as one of its rockstars of science. The magazine featured top researchers in a photo-spread with musicians – in a bid to make science rock as a career choice. It also provided a useful kick-along to efforts to raise much-needed funding for life-saving research.
