Insel didn't get into specifics about what he would be working on at Google Life Sciences, noting in a statement that he is "still working out the final details." He also wrote, "The GLS mission is about creating technology that can help with earlier detection, better prevention, and more effective management of serious health conditions. I am joining the team to explore how this mission can be applied to mental illness." Google Life Sciences has already developed a heart and activity monitor and contact lenses that can read blood glucose levels for diabetics. But the organization has not yet announced any efforts to address mental illness, which one in four adults suffers from every year. Insel, it seems, is an excellent choice to expand the company's purview, finding new technological resources to better diagnose and treat mental illness.
