For twenty five years, from 1986 - 2011, I taught all levels of photography, computer graphics and the history of photography at Pomona College in Claremont, California. In these classes I emphasized the social and historic implications of image making. For the last 45 years I have been been making artworks that make visible the invisible in nature and culture. Some of this work has explored the extraordinary possibilities of using light phenomena to make visible marvelous dimensional possibilities in nature. And some of my work has focused on the military-industrial complex, nuclear industry, the aftermath of the Indochina Wars, the garment industry, museum guards and most recently the prison-industrial complex. I have been an international editor of Leonardo since the mid-1980s and oversee the LABS (Leonardo Abstracts Service) database of MA, MFA and PHD abstracts devoted to the intersection of art/science/technology. During this time I have self-published three books on the artworks and lives of two men incarcerated in California prisons, "Weavers of Varanasi", "Remember Cambodia" about three Cambodian refugee camps in Thailand which I visited in 1990 and 1992, and most recently "Hmong in Transition: China 2004". All of these books can be downloaded from my website.
