Eight postdoctoral stipends in autonomous systems
The Kempe Foundations have granted two years of funding for eight postdoctoral researchers in autonomous systems in a project lead by Erik Elmroth. Autonomous systems consist of software and infrastructure that together with humans provide increased functionality, sustainability, and efficiency for society, such as self-driving cars, industry robots, and socially intelligent computer systems that can help people in their everyday life. Two of the stipends are focusing on autonomous management of clouds. The ambition is to have all postdocs starting in the fall of 2017.
