What is your hidden talent?
I’m a good whistler. As I was growing up, we had a family whistle, so if we were spread out somewhere, like in a grocery store, and heard the call, everyone came. We still do.

What is your instant stress relief?
My dad told me to sing at the top of my lungs in the car on the way home. It helps!

What is your favorite sappy DVD?
The Notebook. The chemistry between Ryan Gosling and Rachel McAdams is beautiful to watch, and the story is sweet.

What is on your bedtime reading list?
On my nightstand are Stephen Hawking’s A Brief History of Time and an issue of Scientific American.

What’s your go-to soothing hobby?
Gardening. I have a living wall of 30 plants — tarragon, rosemary, echinacea. I like to walk alongside it, plucking and chewing.

We hear you love to travel.
I’ve been to Mongolia, Peru, Argentina, India… I try to explore someplace new each time. It feeds the soul, and you bring that back to your everyday life.
