   Biography

Since 1988 I have been a biologist for CH2M HILL in Sacramento, where I work as a wildlife biologist and toxicologist collecting biological samples for contaminant studies and Ecological Risk Assessments. I also prepare biological assessments for endangered species and develop mitigation plans for Section 7 and 10(a) under the Endangered Species Act. I specializes in bird and mammal trapping, biological monitoring, and endangered species surveys. My research has focused on the effects of selenium to wildlife, especially reproductive effects, and I have designed and implemented several field and laboratory studies of reproductive effects of selenium on American kestrels.
