He served for 12 years on the Board of the Great Lakes Protection Fund and is currently a trustee for The Nature Conservancy in Ohio, the Alliance for the Great Lakes, and the Cleveland Water Alliance. Reutter is an aquatic biologist and limnologist, and a frequent lecturer on issues related to the changing Lake Erie ecosystem, harmful algal blooms, nutrient loading, aquatic invasive species, linking environmental health and coastal economic development, Great Lakes research needs and priorities, the importance of science education and research, and the importance of scientists communicating with the public. Reutter received his BS and MS from The Ohio State University in fisheries management and his PhD from Ohio State in Environmental Biology.

Richard Moore

Richard Moore is executive director of the Environmental Sciences Network (ESN) and associate director for academics of the Office of Energy and Environment (OEE) at The Ohio State University. In these roles he helped launch the Global Water and Field to Faucet Initiatives. He designed

the Alpine Nutrient Trading Program, which has been labeled as the “Poster Child of Water Quality Trading” at the 2014 U.S. House of Representatives Hearing on Water Quality Trading. This small trading program was designed to meet


the requirements of an EPA NPDES permit of a cheese factory by using county SWCDs as the broker and having local farmers reduce their phosphorus pollution. The success of this led to expansion of the program to the 21 counties in the Muskingum Watershed. The Alpine program is part of research in the Sugar Creek Watershed near Wooster where OARDC researchers worked with local farmers on grants from NSF, USDA and EPA. Moore serves on the Executive Committee for the Council of Environmental Deans and Directors of the National Council for Science and the Environment and is past president of the Culture and Agriculture subgroup of the American Anthropological Association and NC1190 Catalysts for Water Resources Protection and Restoration: Applied Social Science Research.

2015 OARDC Distinguished Junior Faculty Research Award

Andy Michel

Andy Michel is an associate professor in the Department of Entomology, based on the Wooster campus. He is recognized for his research that seeks to understand how insect pests adapt to rapidly changing selection pressures in agroecosystems, and how this information can help ensure a safer and more productive food supply. He joined OARDC in 2007 as an assistant professor and was promoted in 2013.

Michel runs the Insect Molecular Ecology and Adaptation Laboratory (iMEAL), which focuses on two of the most important insect pests on agronomic crops: soybean aphid

and Western corn rootworm. Michel conducts research that seeks to understand the genetic mechanisms of aphid adaptation and develop improved management strategies to extend the durability and sustainability of aphid-resistant soybeans. His lab leads the way in soybean aphid genetics and molecular biology, publishing more than 20 research papers in journals such as Evolutionary Applications, Genome Biology and Evolution, BMC Genomics, and Heredity.

Meanwhile, in the case of Western corn rootworm (often called the “billion dollar corn pest”), Michel has identified genetic markers linked to Bt resistance—a valuable discovery considering the fact that this beetle has recently evolved resistance to transgenic Bt corn, threatening this extremely valuable tool. This is the first example of an innovative, molecular marker approach for evaluating Bt resistance spread and risk.


Michel’s expertise in population genomics has helped him establish other successful collaborations and multiple publications across CFAES departments. These projects include studying emerging plant disease vectors, bacterial endosymbiont interactions with insects, impact of plant domestication on insect adaptation, climate change adaptation in an Antarctic insect, and conservation of native lady beetle populations. The techniques and expertise of iMEAL have also enabled international collaborations including on Asian citrus psyllid genetics in Mexico and on resistance adaptation in two Brazilian caterpillars.

In total, Michel has published 41 papers while at OARDC and has received more than $5 million in funding as principal investigator or co-PI. He has also delivered 93 presentations and co-written more than 20 fact sheets and bulletins and more than 300 newsletter articles. Additionally, Michel’s outreach and Extension program targets agronomic crop producers and helps them implement appropriate insect-management practices.

The OARDC Distinguished Junior Faculty Research Award consists of a plaque and $1,000 for Michel and $3,000 added to the operating expense account of his OARDC research program for one year.

2015 OARDC Distinguished Senior Faculty Research Award

Steve Schwartz

Steve Schwartz is a professor in the Department of Food Science and Technology, based on the Columbus campus. He is recognized for his research into the role of dietary phytochemicals and functional foods in health, particularly cancer prevention. He joined OARDC in 1996 as Carl E. Haas Endowed Professor of Food Science and Technology and has also been a faculty member in the Interdisciplinary PhD Program in Nutrition since 1997.

Particularly noteworthy is Schwartz’s work in the area of carotenoids, which have been shown to play a role in the prevention of several

types of cancer. He has demonstrated that consuming vegetables with lipids enhances the absorption of carotenoids and bioconversion of pro-vitamin A beta-carotene. Schwartz’s analytical methods to separate and quantify carotenoid isomers are now used by researchers worldwide. Working with David Francis in the Department of Horticulture and Crop Science, he discovered that unique varieties of tomatoes developed at OARDC were significant sources of pro-vitamin A and highly bioavailable lycopene.

Schwartz is now taking his research to a new level, expanding into the groundbreaking field of food and nutritional metabolomics. He was recently selected to lead an OSU Discovery Theme Initiative on this topic, which will make Ohio State one of only a handful of institutions in the United States with this expertise.


Additionally, Schwartz is the director or co-director of four major centers: the Center for Advanced Functional Foods Research and Entrepreneurship (CAFFRE), the Center for Advanced Processing and Packaging Studies (CAPPS, a National Science Foundation Industry University Cooperative Research Center), the Food Innovation Center (FIC), and the Nutrient and Phytochemical Analytic Shared Resource (NPASR, part of Ohio State’s Comprehensive Cancer Center).

Since joining Ohio State, Schwartz has generated more than $22 million in research funding as principal investigator or co-PI. He has also published more than 170 peer-reviewed scientific papers (230 over his entire career), generated 11 patents or invention disclosures, and delivered 125 invited presentations.

Schwartz is a Fellow of both the American Association for the Advancement of Science (AAAS) and the Institute of Food Technologists (IFT). He has received numerous research awards from Sigma Xi and IFT, including the Gilbert A. Laveille Lectureship and Award for outstanding research at the interface of food science and nutrition—presented by the American Society for Nutrition and IFT.

The OARDC Distinguished Senior Faculty Research Award consists of a plaque and $1,000 for Schwartz and $3,000 added to the operating expense account of his OARDC research program for one year.

2015 OARDC Director’s Innovator of the Year Award

Hua Wang

Hua Wang is a professor in the Department of Food Science and Technology, based on the Columbus campus. She is being recognized for her original and significant contributions to the understanding and control of antibiotic resistance, a huge problem impacting food safety, public health and the healthcare industry.

Historically, control of antibiotic resistance had been focused on minimizing the use of antibiotics, but Wang’s work is changing this approach. She has demonstrated that commensal bacteria, including beneficial bacteria, serve as reservoirs and facilitators for the

dissemination of antibiotic resistance in a microbial ecosystem such as ready-to-eat food products. To combat this issue, she built strategic collaborations with the U.S. dairy industry to remove antibiotic resistance gene-filled starter cultures and probiotics used to make yogurt and cheese from major suppliers. This significantly reduced antibiotic resistance bacteria in fermented dairy products on the U.S. market in just a few years, protecting both public health and the reputation of multibillion-dollar fermented dairy food industry.

In the healthcare industry, preventive application of antibiotics has been recently minimized due to concerns about antibiotic resistance. However, Wang showed that lack of early antibiotic intervention increases the chance of developing chronic biofilm-based infections in patients, which are very difficult to treat with antibiotics. Working through the American Society of Microbiologists, Wang organized several conferences, presentations and meetings with government officials. In 2013, the U.S. medical guidelines were modified to recommend


one more dosage of antibiotic after surgical procedures to prevent infection complications, in part due to Wang’s persistent campaign to help reduce antibiotic resistance.

More recently, Wang has shown that oral antibiotic administration causes a rapid increase in antibiotic resistance due to the commensal bacteria in the human gut. By changing antibiotic administration from oral to injection, she has shown that antibiotic resistance can be reduced up to 100,000 times in mice and poultry. While this work still has to be verified in humans, Wang has been working with government agencies and the U.S. Senate to facilitate policy changes and adoption of new directions.

Wang has received one patent and has another pending as a result of her research. She has received funding for antibiotic resistance research and mitigation from the USDA, Battelle, the US-UK Global Innovation Initiative, the Pew Foundation, the Chinese Ministry of Education and many sectors of the food industry including dairy, soybean and pet food.

The OARDC Director’s Innovator of the Year Award consists of a plaque and $1,000 for Wang, and $2,500 added to the operating expense account of her OARDC research program for one year.
