+How did you get interested in transportation? 
The first time I rode the Washington Metro when I was 11 years old I was amazed at the sheer number of people who can travel at once. It was my first experience with a large city public transit service and got me interested in how transportation works with urban planning.

+Personal life philosophy? 
Never be afraid to question the world around you. 

+How do you relax? 
I can usually unwind with an easy run listening to my favorite music, or doing a little yard work. Alternatively, I certainly don’t mind reading on the back porch or vegging on the couch watching TV. 

+Best advice you’ve ever received? 
Perennial wisdom from my grandmother: “Don’t sweat the small stuff...” 

+Favorite fast food chain? 

+Uber or Lyft?
