I consciously think about the ethnicity of every character that I create and cast. But one thing that is equally important is quality representation.

My dad even likes to give me career advice. I'll let him know about some offers about films and TV shows that I get, and he'll ask me questions like, 'What's the money like?' and 'Who got this for you - was it your agent or manager, and what are they getting out of this?'

My background is in biology. Before getting into the family business, I worked at the Predatory Bird Research Group at the University of California at Santa Cruz, fundraising for them.

The citation for the 1971 Nobel Prize in Chemistry reads, 'for contribution to the knowledge of electronic structures and geometry of molecules, especially free radicals,' and therefore implies that the Prize has been awarded for a long series of studies extending practically over my whole scientific life.

The decline of particle physics in the U.S. is really a symptom of the erratic and sometimes anti-scientific attitudes in Washington and the incompetence of Congress in managing science.
