Whenever I give an interview, I ask how long a piece the journalist is aiming for. Then I TRY to keep myself to reasonable length....but I often fail, because nature and science are SO COOL. Thanks @elisecutts.bsky.social for making me feel better about it!

It's always a great sign when an interview with a scientist starts like this: Me: Hi there, thanks for talking to me. I'd like to ask you some questions about [thing]. Scientist: OH MY GOODNESS I LOVE [thing]!!! I could talk about [thing] for hours!!!!!

We couldn't be happier to welcome Kate to this new role!
