My life is not all about physics, so here are other things I care about/enjoy.
Animals: We rescued our cats from the street in Spain, and now they live with us in Pasadena. I love my cats, but I also care deeply about animals in general. I am quite obsessed with taking pictures of squirrels in the Caltech campus.
Traveling: I really enjoy being a physicist, because it is a job that allows me to see very different parts of the world. Below, a picture from the cusp of Villarica volcano in Chile, and a couple of closer destinations: San Francisco and Joshua Tree National Park.
Rollerblading: I have been rollerblading since I was a kid. I like to learn new slalom tricks. I also use my rollerblades as a mean of transportation.
