Dr. Marilia Chiavegato HeadshotDr. Marília Chiavegato
Assistant Professor

Dr. Chiavegato started her academic career in Brazil, where she received an MS in Applied Chemistry, with a focus on agriculture and the environment, at the University of São Paulo. In 2014, she graduated with her PhD in Animal Science from Michigan State University. After returning to Brazil for a postdoctoral position at her alma mater, she began her current position as an Assistant Professor at Ohio State University in the Department of Horticulture and Crop Science, with a joint appointment in the Department of Animal Science. An overarching theme of Dr Chiavegato’s work is to improve the ecological sustainability of agricultural systems without sacrificing farm output. Through her systems-approach research, in which different aspects of an agricultural ecosystem are monitored, she aims to design effective agricultural land-management strategies.

Dr. Jessica Cooperstone HeadshotDr. Jessica Cooperstone
Assistant Professor

Dr. Cooperstone is an Assistant Professor in the departments of Horticulture and Crop Science, and Food Science and Technology, and part of the Foods for Health Discovery Theme Initiative at The Ohio State University.  Working at the intersection of plant, food, and nutritional sciences, her goal is to develop fruit and vegetable varieties that are purposefully designed for enhanced human health, backed up by clinical trial data and worthy of government supported health claims. Her interdisciplinary research group works to better understand 1) how genetic and environmental factors affect the biosynthesis of phytochemicals in crops, and 2) how these compounds affect human health.  Projects in the Cooperstone Lab combine analytical chemistry (both through traditional chemical analyses, and broader untargeted chemical profiling) with plant genetics/genomics, transcriptomics, microbiome data, sensory science, and measures of health outcomes and utilizes bioinformatics-based approaches.

He is developing novel analytical tools for food evaluation, and he applies NMR spectroscopy for the discovery and characterization of compounds with high commercial and nutritional value that can be produced from low-cost sources, such as food industry waste. In addition, he uses a multi-disciplinary research approach that combines spectroscopy, metabolomics, gene expression profiles and microbial analysis to investigate the interaction between nutrition and microbiome and how this is related to health and disease. His research findings have been published in 47 referred journal articles, and he has contributed to 4 book chapters, and 1 scientific bulletin. His publications appeared in journals with average impact factor of 6.5, while his research work over the past decade has been recognized worldwide through invitations to speak at national and international conferences, educational institutes, and governmental agencies.

Dr. Shoshanah Inwood HeadshotDr. Shoshanah Inwood
associate professor

Dr. Inwood is an Associate Professor and rural sociologist in the School of Environment and Natural Resources. Her integrated research and extension program explores the impact of national, state and local efforts to create economic development through food and agriculture and addresses the question of who will be the next generation of farmers in light of a shrinking and aging farm population. Her work focuses on three major themes: 1) Health and well-being in the food and agriculture sector, 2) Social factors affecting farm viability, and 3) Community and economic development through food and agriculture. In recent years, her work has focused on the needs farm families have for accessing adequate health insurance and childcare, exploring the contribution of local food systems to rural community development, and food system resilience in the midst of disasters and disruptions.

Dr. Zoë Plakias HeadshotDr. Zoë Plakias
assistant professor

Dr. Plakias is an agricultural and food systems economist. She uses microeconomic theory and econometric methods to study: (1) the motivations of stakeholders and welfare implications in domestic supply chains aim to produce and distribute food in ways that are more fair, healthy or environmentally sustainable than conventional supply chains; (2) the role of market power in the agricultural supply chain in the context of farm organizations and farmer collective action; and (3) the interactions of farmers and food system stakeholders in farm organizations, cooperatives and social networks both within and outside markets, and their relationships to market outcomes. She also teaches undergraduate courses in Ohio State’s Agribusiness and Applied Economics (AAE) and Environment, Economy, Development, Sustainability (EEDS) majors, and conducts outreach to agricultural and food system stakeholders in Ohio and nationally.

Dr. Christopher Simons HeadshotDr. Christopher Simons
associate professor

Dr. Simons earned his undergraduate degree in Biology from the University of Oregon, his Master of Science degree in Physiology from Portland State University in Portland, OR and his Doctoral Degree in Sensory Science from the University of California, Davis. Subsequently, Chris completed post-doctoral fellowships in the Laboratoire de Neurobiologie Sensorielle [Sensory Neurobiology Laboratory] at the Ecole Pratique des Hautes Etudes in Paris, France and the Unités de Formation et Recherche de la Odontologie [Dental School] at the Universite Paris 7. From 2004 through 2012 Chris led the Sensory Research function at Givaudan Flavors Corp. and joined the faculty in the Department of Food Science and Technology at the Ohio State University in 2013. Chris’ research interests use a multidisciplinary approach to understand perception of foods and how they are processed to influence reward and ultimately behavior. One outcome of this research is to identify the neural and physiological correlates associated with perception, food reward and behavior through the use of a variety of implicit and explicit methodologies including human sensory testing, electrophysiology, and behavioral measurements. Another outcome of his research is to leverage the knowledge gained from these types of investigations into the development of new methodologies that can be utilized by the Food and Beverage Industry to improve the product development cycle. Chris has been recognized by the Association for Chemoreception Sciences—the leading international society on chemosensory research—with the Barry Jacobs Memorial Award for Research in the Psychophysics of Human Taste and Smell.
