"I worked as the lead analyst and senior instrumentation specialist at the University of Wisconsin - Madison, Soil and Plant Analysis Lab for more than 15 years. In addition, I have long experience in scientific research with a focus in the area of environmental fate of pesticides and the concentration of heavy metals in the environment. I also collaborated in research focusing on the impact of dietary changes on the incidence of kidney stones. Lately, I have been involved in research in the area of plant pathogenic nematodes and their control. Although I do not have teaching responsibilities, I have been training University of Wisconsin students and staff on the use of analytical instrumentation and analytical methods. "
