Dr. Raven Hanna has Ph.D. in molecular biophysics and biochemistry and did her postdoctoral research at Berkley. But these days you won't find her in any lab. A few years ago, she traded her science career for an creative one. She's been making science-inspired jewelry ever since.

Raven's molecular pieces are inspired by the neurotransmitters that she finds interesting, and ones that can be applied to daily life. Her work is a celebration of science, art, life and the universe.
