We continue to face challenges – from climate change to cyber-security, poverty to pandemics – and the confluence of emerging technologies is set to change our world in ways that are yet unforeseen.

Scientists have an important role to play in both helping to understand and develop solutions to the challenges raised by the Fourth Industrial Revolution, the theme of this year’s Annual Meeting of the World Economic Forum in Davos.

Science and technology pervade modern society, and the challenges they pose are no longer purely scientific. They have ethical, social, political and economic dimensions, and that is why scientists need to come together with different groups of stakeholders.

The scientists below will all be bringing their perspectives to our meeting of leaders from every sector in Davos next week.
