Most of my professional life has been spent as a research biologist and science writer in plant biology at the University of California, Santa Cruz, so many of my paintings are botanical.  Here, I’ve arranged my paintings according to subject beginning with Botanica, Animals, and Birds. A number of paintings in the Landscapes section focus on California. Paintings under Allegory and Symbolism are meditations on the syncretism between ancient concepts and modern reformulations, often inspired by Amerindian sources.   Another series engages with Fantasy. Here are surf cats, mysterious journeys, and witches whose occupations provide explanations for natural phenomena.   the cover illustration of my novel Libra, the Cat Who Saved Silicon Valley, is included here.

A recent publication in science history, co-authored with Lincoln Taiz, is Flora Unveiled: The Discovery and Denial of Sex in Plants, Oxford University Press.
