I'm really fascinated right now with how sufaces, foliations, Culler-Vogtmann outer space, tropical geometry, & physics all fit together. So we have a surfaces, tropical geometry, & physics working group. Today I talked about the CP coordinates.

Something extraordinary for me about the IAS is the intergenerationality & inclusion of "wise elders." I will always treasure the special bond Pierre & I developed with the greatests of greats, Karen Uhlenbeck. Our many meals, math & life conversations, something very special...

Always wonderful to see a former student thriving & sharing that they'll be at your location! Howie Hong at IAS!

Among last week's IAS shenanigans was trying to reenact an Oppenheimer scene with Professor Flores. I chose to asssume that in reality there was actually a dog present in that moment of history.

PhD advisor Lee Mosher & his current student Sarasi Jayasekara visited me at IAS today for Lee's talk. Really wonderful talk & day!

Pierre enjoyed learning about buildings this week from Petra Schwer!

This beautiful mathematical story was a highlight of the week for sure! Thanks Rob Silversmith!

Really great visiting Yale earlier this week & chatting with Eduardo Reyes there!

Episode 2 today with her collaborator also. Very fun & exciting conversations!

So much going on that I forgot to share that Chi Cheuk Tsang & I have a new preprint! Really fun project, where we give a "cubist" decomposition of the collection of axes for a fully irreducible & use it for the conjugacy problem. arxiv.org/abs/2503.16360

There's a new Dr. in the house! Lee Mosher's final PhD student (Dr. Sarasi Jay, @sarasi.bsky.social ) has successfully defended her formidable thesis!

And they're multiplying!

The turtles in Princeton have come out of brumation! It must be spring!

Very special treat to get to tell Karen Uhlenbeck about geodesics in Culler-Vogtmann outer space today & for her to share some of her wisdom in return. Some heros are even better in real life.

Looking who I found around Princeton/IAS this past week! @haydeelindo.bsky.social is even more lovely in person than online!

Very proud of PhD students Paige Hillen finishing 4 papers & giving a series of talks on her research. She'd be an fantastic postdoc & is applying right now! sites.google.com/view/paigehi...

So many patterns involving Pascal's triangle!

And my boardwork always seems neater to me inside my brain, but I tried to remember to code color-coding with shapes also & the math is so pretty!
