OARDC Compost Research Group . . . Who we are . . .

Frederick Michel

Dr. Frederick C Michel, Jr. is an associate professor in the department of Food, Agricultural and Biological Engineering (FABE) at the Ohio Agricultural Research and Development Center (OARDC) in Wooster- Ohio . He received his Ph.D in Chemical Engineering with a minor in Microbiology from Michigan State University . His research areas are focus on improving the processing of agricultural and industrial organic byproducts through the development of new or improved bioprocessing technologies. Specific research activities include the development of DNA/RNA based analytical tools for the investigation of microbial community structure and function in composts and amended soils; engineered processes for efficient conversion of dairy and hog production wastes into composts and other value-added, transportable and stable products that reduce water and air pollution; and characterizing the effects of composting and other waste management processes on xenobiotic chemical fates, plant disease suppressive microorganisms, antibiotics and human and animal pathogen persistence.

Dr. Harold M. Keener is a professor emeritus and associate chair in FABE at Wooster. He received his Ph.D. in Agricultural Engineering from The Ohio State University in 1973. His areas of expertise include systems analysis with specializations in energy metabolism of living systems, operations research, control theory, and heat and mass transfer.He also works with composting, biomass combustion, grain drying, livestock housing, and manure management.

Warren Dick

Dr. Warren Dick is a professor of Soil and Environmental Chemistry in the department of Environmental and Natural Resources at OSU; he received his Ph.D. in Soil Science from Iowa State University in 1980. His research areas cover microbial ecology, no till crop prodcution, coal combustion products, solid waste management, soil microbiology and soil biochemistry. His soil microbial ecology program is focused on understanding and manipulating soil microbial communities to produce practical solutions for bioremediation, biosecurity and biogeochemical cycling.

Dr. Daniel A. Herms is a professor and chair of the department of Entomology in OSU-OARDC and a State Specialist with Ohio State University Extension.  He also serves as the Associate Chair of the Entomology Department.  Herms’ research and extension programs address (1) plant-insect interactions including chemical ecology of plant defense, (2) IPM for ornamental landscapes, urban forests, and nurseries.  He is an avid butterfly gardener and scuba diver, but has yet to figure out how to combine the two.  He received his PhD in Entomology with a specialization in Ecology and Evolutionary Biology from Michigan State University in 1991.  Prior to joining Ohio State University in 1997, Herms worked for 13 years at the Dow Gardens in Midland, Michigan, where he directed their pest management program.

Jeff LeJeune

Dr. Jeffrey T. LeJeune is a professor and head of the Food Animal Health Research Program in the Department of Veterinary Preventive Medicine at OSU. His research areas of interest include preharvest control of human foodborne pathogens and antimicrobial resistant bacteria in the animal host and the environment. Current projects focus on the effects of diet composition on the magnitude and prevalence of E. coli O157 in cattle and the identification of practical, on-farm methods to reduce bacterial contamination of livestock drinking water. Additional professional interests include other bacterial zoonoses and infectious diseases of farmed finfish.

Dr. Zhongtang Yu is an associate professor in the department of Animal Sciences at OSU. He obtained his Ph.D. in Molecular Biology from New Mexico State University. Dr. Yu is interested in ecological studies of microorganisms inside (mainly the gastrointestinal track) and outside (the surrounding environments) of food-producing animals that are important to animal nutrition and health. Another thrust of his research is ecological studies of antibiotic resistance originating from food-animal production. In recent years, concern has increased on the impact of agricultural use of antibiotics, especially in food animals, on human health.
