So, do you get your fix of mentoring/teaching/research through that; it perhaps through FOSS involvement or ...? Not suggesting you have to, just your comment suggested that was/is your passion.

A few things!

- peer-review for journals and conferences

- a fellowship and guest lectures

- collaborating with my previous co-authors in my own time

- publishing educational content

and you're right, it is something I'm passionate about. The list above is my attempt to stay involved, but I'm not sure how that will work out long term. Hopefully I will find something sustainable.
