Today, I’m delighted to become an honorary member of the #IowaState University chapter of Phi Beta Kappa. A big thank you to Peter Orazem and the other officers of the chapter. The student initiates are an impressive and amazing array of talent!

Thinking of Dr. Wojtek Dziembowski - a kind soul whose wisdom and joy made us all better asteroseismologists and people - on his passing earlier this week. Such a privilege to have been able to work with and learn from him, & enjoy many visits together in Poland and at conferences around the world.

A lovely end to the first week of the Spring 2025 term at #IowaStateU
