I spent more than 20 years of my professional career researching and developing renewable energy sources.
I enjoyed like nothing else working in pure math, discovering new formulas.
People come to me with their passion about transportation, about education, about health care, about agriculture, the dairy industry, the almond growers. I'm just a kid in a candy store, learning and eating up all this different knowledge.
I spent 10 years working on a math Ph.D., and I finally got kind of good at it.
In 2004, I ran for Congress and lost. In 2006, I ran again and won - defeating Richard Pombo, a seven-term Republican incumbent.
