Barb is a layperson, retired from medical transcription after twenty-five years and enjoying a new chance to explore earth science (which she studied as an undergraduate back in the Eighties) thanks to the Internet and (finally) some free time. She has been blogging at https://flighttowonder.com/ for years, tweets at Twitter.com/@bjdeming, has a new book out, and hopes to make this science writing gig full-time in 2021.
