About Me


When I’m not studying supernovae, I enjoy walking to the top of things, climbing to the top of (much shorter) things, and performing no net work on (terrestrial) Fe-56.

Empire and Wrath of Khan were the best.

I am married to the wonderful Ashley Rubin, and our pack has two dogs.








My favorite job that I’ve had before becoming a professor was when I was a reactor operator (eventually becoming a senior reactor operator) at the Reed College reactor.
