We supports experts in fields like healthcare, we also collaborate with Google teams to apply our cutting-edge research to products and infrastructure used by many millions of people across the world. Our technology has led to major breakthroughs in the energy efficiency of Google’s data centres, reducing the electricity needed for cooling by 40%, while our WaveNet technology is now used to generate voices for the Google Assistant. We also continue to work in partnership with other teams, such as Google Play. Working at Google scale gives us the opportunity to learn how to apply our research to truly global and complex problems, to validate the impact we can have on systems that have already been highly optimised by brilliant computer scientists, and - as our data centre work shows - to achieve amazing real-world impact too.
