We begin with Elizabeth Chen, who successfully defended her PhD dissertation last Friday in East Hall on the UM campus.

Chen exhorted the assembled mathematicians to paste together plastic pyramid shapes with gummi putty to help them get an intuitive feel for the shapes: “It’s not so scary!” she admonished them.
