Deanna Osmond
Deanna Osmond works at the interface of nutrient
management, conservation practices, and water quality
in the Soil Science Department at North Carolina State
University. She received her BS in Agronomy and
Anthropology from Kansas State University, her MS in Soil
Science from North Carolina State University, and her PhD
in Agronomy from Cornell University. For the past 25 years
she has conducted field- and watershed-scale experiments to find conservation
practices that reduce nutrient loading, especially in impaired watersheds; as an
extension specialist she has then used the information to extend this information
to farmers and agency personnel. Recently, she led a national team to determine
the effectiveness of conservation efforts at the watershed scale across the
United States and more importantly, transfer the lessons learned from this work
to multiple stakeholders.

Jay Martin
Jay Martin is a professor of ecological engineering who
analyzes and integrates coupled human and natural
systems. He serves as the Lead Faculty for the Global
Water Initiative and the Field to Faucet Program at Ohio

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 resistancea
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.

2015 oardc annual research conference

Michels 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, Michels 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.

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 Schwartzs
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 betacarotene. Schwartzs 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 provitamin 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.

2015 oardc annual research conference

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 States 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 nutritionpresented 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.

Innovator of the Year Award
Hua Wang

Photo by Ken Chamberlain

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 Wangs 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-toeat 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

12

2015 oardc annual research conference

one more dosage of antibiotic after surgical procedures to prevent infection


complications, in part due to Wangs 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 Directors 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.
