Reason for Seeking Public Office:

"I never imagined I'd be interested in politics. Most of my career has been devoted to research and training scientists and conservationists, and lending my voice to climate advocacy efforts in recent years. But we scientists, at our core, are problem solvers, and the problems Wyoming faces today call for a bold vision, one informed by facts, one with a long term view, and one that a scientist like me is uniquely poised to lead."
