Mark Borchardt, Ph.D is a Research Microbiologist in the Environmentally Integrated Dairy Management Research Unit in Marshfield, Wisconsin. Prior to this, he was a Research Scientist for 15 years at the Marshfield Clinic Research Foundation. His published research involves the areas of groundwater-borne viruses, methods of pathogen detection in the environment, and human health as related to drinking water and sanitation. In his position, Dr. Borchardt is investigating solutions for mitigating the environmental transmission of pathogens found in livestock manure.
Dr. Borchardt served on the drinking water, homeland security, and state of the environment committees of the US Environmental Protection Agency Science Advisory Board.
John Brooks, Ph.D. is a research microbiologist with the USDA – ARS Genetics and Sustainable Agriculture Research Program and Mississippi State University who promotes the maintenance of sustainable agricultural environments though a focus on pathogens and antibiotic resistance, microbial ecology, and quantitative microbial risk assessment.
John Chastain, Ph.D. is currently a Professor and Extension Agricultural Engineer at Clemson University in South Carolina. He develops and implements extension and applied research programs in animal waste management and production systems for swine, poultry, and dairy facilities. Much of his work has been related to solid-liquid separation, land application of animal manure, composting, and manure system design. Prior to moving to South Carolina he was on faculty at the University of Minnesota where worked with outstanding faculty and Extension Agents on all aspects of dairy facilities planning and design. A native of Georgia, he received his BS in Agricultural Engineering from the University of Georgia, and his MS and his Ph.D. degrees in Agricultural Engineering from the University of Kentucky.
Shulin Chen’s research emphasis is in the area of Bioenergy and Bioproducts Engineering. He leads a research team of over twenty scientists, graduate students, and visiting scholars working in the field of industrial biotechnology; developing bioconversion processes and systems for the production of biofuel, bioenergy, and bioproducts.
Clinton Church, PhD is a Research Chemist for USDA-Agricultural Research Service, stationed in University Park, PA. His background and research interests are in the inter-relationships between water, chemistry, and microbiology. His research currently focuses on metals, nutrients, and emerging contaminants derived from agricultural practices. Clinton joined USDA-ARS in 2007 after five years work as a Research Hydrologist for the U.S. Geological Survey in San Diego CA. His research for USGS focused primarily on water-quality issues related to public water supply. Clinton holds a Ph.D. degree in Environmental Science and Engineering from the Oregon Health and Science University, and Bachelors and Masters degrees from the University of Montana. Before entering graduate school, Clinton taught math and science in Montana.
Rebecca Larson, Ph.D. is an Assistant Professor in the Biological Systems Engineering Department at the University of Wisconsin-Madison and a Biowaste Specialist with the University of Wisconsin-Extension. Dr. Larson performs research and extension/outreach applications of biowaste management including handling, treatment, and processing of all types of biological waste streams and in particular manure. Her work is largely comprised of manure management systems focusing on increasing the profitability and sustainability of food production systems while simultaneously reducing the environmental aspect. Dr. Larson is a Biological Systems Engineer by training, earning her B.S., M.S., and Ph.D. degrees from the Department of Agricultural Biosystems Engineering at Michigan
