I'm a physicist and the program lead for ergodicity economics at the London Mathematical Laboratory. I'm also an external professor at the Santa Fe Institute.
Ergodicity economics questions the assumption that expected value is a relevant quantity in economic models. For historical reasons, it is often assumed that this is so, but it's only true in some cases. I'm currently working on a popular-science book and on a textbook about the topic.
