Before pivoting to finance, John Carlson studied for a PhD in meteorology at MIT. He even wrote a dissertation that he never submitted. However, he's never lost interest in climate. In January 2016, John had the opportunity to take part in an expedition to Antarctica aboard the National Geographic Explorer along with researchers affiliated with National Geographic and MIT. We caught up with John after his trip for a deep dive into his journey to the poles, and his path from PhD candidate to internationally renowned money manager.
