For me, solving grand challenges is about making real progress and being open to new paradigms. The grand challenge of solar energy absolutely needs the support of research scientists in the lab, but in today’s society it also needs the support of governments, industry, and the public. As an engineer with a diverse background, I am confident that I will continue to contribute towards this challenge, both in creating the technology that can change the world, as well as helping cultures to embrace the new technology. The engineering grand challenges are truly that – grand challenges – and any focused effort, no matter how technical, helps move the world forward.
