My #introduction post was so long ago that I've changed jobs and Tootsville has blown up, so #AllowMeToReintroduceMyself
Professionally, I'm an astronomer at Harvard & Smithsonian studying black holes at the dawn of time and working on the #Chandra X-Ray observatory. #Astronomy #Astrophysics #Astrodon
Personally, I like #running, #hiking, #climbing, #camping, etc.
Lately, I've been on a real big #PublicTransit #Rail #Transit kick on here -- #Trains and #Mastodon both go Toot Toot!
