I explore the world looking for interesting engineering stories which explore complex issues in interesting ways. In between episodes I'm doing a PhD in space robotics at MIT. My website is https://www.atomicfrontieronline.com, I occasionally tweet from https://twitter.com/AtomicFrontiers, and you can join the Atomic Frontier Discord server to talk about cool engineering stuff at https://discord.gg/4QZc3jYdTR.
