Education:
1993, B.A., Biology, Silver Lake College, Manitowoc, Wisconsin

Primary Responsibilities/Activities:
As a biologist in the Aquatic Ecosystems Health branch, my research projects primarily support the effort to gain US Food and Drug Administration (FDA) approval of drugs used in aquaculture. My focus has been in the areas of target animal safety, tissue residue depletion, and drug efficacy. However, I also participate in studies that investigate the environmental fate of various drugs and chemicals, lend assistance to the Invasive Species work group, and provide back-up in our Fish Culture facility.
