I want to give a special shoutout to those that donated to or advocated for childcare at the #JMIH25 meeting. Because childcare is available on site, I have been able to attend the meeting and present my research. It is a lifeline for early career researchers, particularly women!

Tree space and a new ray-finned fish out today! We delve into how methods to visualize the forest of phylogenetic tree space can be used to address the rogue taxon problem. Shout out to my co-authors and advisors Michelle Stocker and Michael Gottfried.

My latest for @nytimes.com! For 40 years, paleontologists have grappled over whether a small tyrannosaur — named Nanotyrannus — was its own animal, or simply a teenage T.rex. The debate has been ... contentious. Which is why it's so fun to finally be able to say this:
Folks? Nanotyrannus is real.
