Everybody after Fukushima had to reassess the safety of nuclear. When I set out to design a reactor, I knew it had to be passive and intrinsically safe.

When I was 10 years old, that nuclear spark hit me. Whatever it may be, I really don't know what it was about nuclear science, but whatever it was that triggered that interest, it stuck. I went after that one with a passion.

I developed a counterterrorism device that's revolutionizing the way we detect nuclear materials.

I think there's something really poetic about using nuclear power to propel us to the stars, because the stars are giant fusion reactors. They're giant nuclear cauldrons in the sky.

providing safety, well i think providing security doesn't mean your keeping me safe

My holy grail is fusion energy. Nuclear fusion has little to no radioactive waste. It's clean. It's very abundant. The fuels are everywhere. There are problems with fusion.
