This season on Working, we’re speaking to individuals employed in fields potentially imperiled by the Trump presidency. These are the stories of people doing difficult but important jobs—jobs that may get much more difficult and much more important in the years ahead.

Professor Matthew Kroenig is a Nuclear Nonproliferation Expert and an Associate Professor in the Department of Government and School of Foreign Service at Georgetown University. He spoke with Jacob Brogan at Georgetown about how he got involved in nonproliferation, and a project to help prevent 3D printing of nuclear weapon components.

Then, in a Slate Plus extra, Kroenig talks about nuclear weapons in the movies. If you’re a member, enjoy bonus segments and interview transcripts from Working, plus other great podcast exclusives.
