Personal

The non-physics half.

Cats

I love cats. Several of them run the household and consider my desk, keyboard, and any warm laptop to be sovereign territory.

Under the sky

Observational astronomy — the oldest way of doing physics, and still the most humbling.

Moving around

Running, and ping-pong whenever there’s an opponent brave enough.

The garden

A small garden that asks for patience and returns it — a good counterweight to a screen.

With Charlie Kane and Gene Mele

My PhD advisors at Penn, and two of the physicists I admire most.
