Dr. Khara Grieger is currently an Assistant Professor and Extension Specialist in Environmental Health & Risk Assessment. Her research focuses on best practices for risk assessment, risk management, and stakeholder engagement related to the governing of emerging risks and new technologies. For example, she is currently the Project Director for a USDA/NIFA-funded grant that investigates the societal implications of nanomaterials used in food and agricultural sectors. She is also the PI of a grant that aims to grow the field of risk science in the Research Triangle Park area of NC, through funding provided by the Society for Risk Analysis. Further, she is a Co-PI in a NC State-funded GRIP4PSI grant that develops new technologies for use in the sweetpotato industry in North Carolina (Williams = PI) in which she leads the stakeholder engagement efforts, and Co-PI on a NSF-funded grant that focuses on governance of climate management technologies (Borsuk = PI). She is also involved in the NSF-funded Research Triangle Nanotechnology Network (RTNN) housed at NC State University (Jones = PI), a member of the Center for Human Health and Environment (Smart = PI), and Executive Committee Member in the Genetic Engineering and Society (GES) Center at NC State. In addition to research, Dr. Grieger also serves as an external advisory board member for a large European project focused on risk governance (RiskGONE), is the US Co-Chair for a US-EU Risk Management & Control Community of Research (COR) focused on nanomaterial risks, and an External Advisory Board member for the Town of Cary, NC.
Prior to joining Applied Ecology, she served as a Senior Research Scholar in the GES Center from March 2019 through June 2020. She also was a Senior Environmental Research Scientist at RTI International in the Health and Environmental Risk Analysis program (2012-2019), a Duke University Scholar (2017-2018), and Adjunct Professor at Meredith College (2014).

The Science and Technologies for Phosphorus Sustainability (STEPS) Center is a convergence research hub for addressing the fundamental challenges associated with phosphorus sustainability. The vision of STEPS is to develop new scientific and technological solutions to regulating, recovering and reusing phosphorus that can readily be adopted by society through fundamental research conducted by a broad, highly interdisciplinary team. Key outcomes include new atomic-level knowledge of phosphorus interactions with engineered and natural materials, new understanding of phosphorus mobility at industrial, farm, and landscape scales, and prioritization of best management practices and strategies drawn from diverse stakeholder perspectives. Ultimately, STEPS will provide new scientific understanding, enabling new technologies, and transformative improvements in phosphorus sustainability.
This proposal puts forth a timely and multi-faceted approach to assess the societal implications of genetic engineering (GE) and nanotechnology used in food and agriculture (agrifoods) and identify strategies to ensure the sustainable futures of agrifood technologies according to diverse stakeholder perspectives. There are three primary objectives: 1) Assess societal implications and improve decision-making of GE- and nano-agrifood products through benefit-risk evaluations; 2) Identify strategies to ensure sustainable development and use of GE and nano-agrifoods through multi-stakeholder engagement and exchange; 3) Develop interdisciplinary education and training opportunities to better evaluate societal implications of new and novel agrifood technologies. Key project outcomes will help policy-makers and other decision-makers i) make informed decisions on GE- and nano-agrifoods, particularly in contexts of benefits and risks, ii) understand societal implications of GE- and nano-agrifoods based on stakeholder perceptions and attitudes, and iii) identify best practices for evaluating societal implications of new and novel agrifood technologies according to diverse perspectives.
A Pipeline of a Resilient Workforce that integrates Advanced Analytics to the Agriculture, Food and Energy Supply Chain
In the project ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œImplications of Solar Radiation Management for Collective Climate Action,ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â NC State will be responsible for the following: ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ Assist in the formulate a general theory of behaviour for actors confronting a collective-risk social dilemma with the option of deploying a risky solution. In this work, NC State will review proposed approaches put forward by Duke University and provide comment and recommendations. NC State will also review any work products from Aim 1, provide suggestions and recommendations, and disseminate the resulting outcomes through NC State research networks, including NC State's interdisciplinary science, technology and society initiatives. ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ Assist in the design of experimental games to test theoretical model predictions and assist in the formulation of a resulting behavioural model. In this work, NC State will review proposed approaches by Duke University and provide recommendations on the technical content of the experiment to ensure the desire outcomes will be achieved. NC State will also review any work products from Aim 2, provide suggestions and recommendations, and disseminate the resulting outcomes through NC State research networks ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ Lead the teamÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s efforts to translate and disseminate of our theoretical, simulation, and experimental tools and results to other domains of science and technology policy. For example, we anticipate that results and approaches will not only be applicable to the use of SRM but will also be highly relevant to the management of other ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œquick fixÃƒÂ¢Ã¢â€šÂ¬Ã‚Â emerging technologies, such as gene drives to eradicate insect-borne diseases or engineered nanomaterials deployed for environmental remediation. ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ Assist Duke University in preparation and finalization of project outcomes, resulting manuscripts, policy-brief(s), and dissemination efforts.
Inconsistent quality and aesthetics in agricultural crops can result in increased consumer and producer food waste, reduced industry resiliency and decreased farmersÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ and growersÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ profit, poor consumer satisfaction, and inefficiencies across the supply chain. Although there are opportunities to characterize and quantify sources of phenotypic variability across the agricultural supply chain - from cultural practices of growers and producers to storage and handling by distributors - the data available to allow for assessment of horticultural quality drivers are disparate and disconnected. The absence of data integration platforms that link heterogeneous datasets across the supply chain precludes the development of strategies and solutions to constrain variability in produce quality. This projectÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s central hypothesis is that multi-dimensional produce data can be securely integrated and used to optimize management practices in the field while simultaneously adding value across the entire food supply chain. We propose to develop multi-modal sensing platform along with a trust-based, data management, integration, and analytics framework for systematic organization and dynamic abstraction of heterogeneous data across the supply chain of agricultural crops. The projects short term goals are to (1) engage growers to refine research and extension priorities; (2) develop a first-of-its-kind modular imaging system that responds to grower needs by analyzing existing and novel multi-dimensional data; (3) establish the cyberinfrastructure, including analytics and blockchain, to make meaningful inference of the acquired data as related to management practices while ensuring data security; (4) deploy the sensing system at NCSUÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s Horticultural Crops Research Station in Clinton, NC and on a large-scale system at a major commercial farm and distribution facility, and (5) extend findings to producers and regulators through NC Cooperative Extension. The proposed sensing and cyberinfrastructure platforms will be crop-agnostic and our findings will be transferable to other horticultural crops produced in NC and beyond.
