Agricultural Center (OHCEAC) at Ohio State University, reporting to
OHCEAC director Dr. Chieri Kubota.
Carly manages communications, media, events, and
donor and stakeholder relations for
OHCEAC. She also works closely with OptimIA’s multi-state project team
of researchers and extension specialists to support their outreach and
Ian Kelly is an undergraduate genetics and horticulture double major at Purdue University under the advisement of Dr. Cary Mitchell.
Ian works with Dr. Mitchell’s graduate students (Fatemeh Sheibani and Michael Gildersleeve) with their experiments including improving the efficiency of LED fixtures based on their distance to the crop canopy and incorporation of far red light into the output spectrum. His current project is researching mats of different material to determine an alternative to a coco coir and perlite mixture in order to make commercial production easier.
Energy-efficient indoor production of leafy-greens
Fatemeh Sheibani is a post doc research assistant at Purdue University under the supervision of Dr. Cary Mitchell. She also received her PhD from Purdue University in 2023, under the supervision of Dr. Mitchell.
She has been working to develop strategies to enhance energy-efficient indoor production of leafy-greens by leveraging unique properties of light-emitting diodes (LEDs) for sole-source lighting. To optimize conditions for indoor leafy-greens production, interaction of LED lighting with other environmental parameters including temperature and CO2 concentration are taken in to account. Close-canopy lighting, targeted lighting, and phasic co-optimization are the main OptimIA strategies that have been under investigation in the Mitchell lab.
Improving yield, color, and flavor of leafy greens and herbs grown indoors with precise radiation intensity, temperature, and carbon dioxide management
Sean Tarr is an M.S. student at Michigan State University under the advisement of Dr. Roberto Lopez.
He is quantifying how temperature alone or its interaction with radiation intensity and/or carbon dioxide concentration influence leafy green and herb yield, color, and post-harvest life. Production models that include radiation intensity, temperature, and CO2 will provide growers with the best recipe to improve leaf unfolding rates, color, flavor, and post-harvest lon/gevity.
Tipburn Ecophysiology and Management in Indoor Farming
John Ertle received his PhD from the Ohio State University in 2023, under the advisement of Dr. Chieri Kubota.
He investigated the ecophysiological insight of tipburn, an environmental nutrient disorder problematic in lettuce, and developed novel microclimate control strategies to mitigate risks of tipburn. John’s project also included commercial cultivar screening for tipburn sensitivity and dissemination of information and decision support tools to stakeholders.
Reducing Tipburn in Lettuce Grown in an Indoor Vertical Farm: Comparing the Impact of Vertically Distributed Airflow vs. Horizontally Distributed Airflow in the Growth of Lactuca Sativa
Christopher Kaufmann is a former MS student who graduated from the University of Arizona in 2023 while under the advisement of Dr. Murat Kacira.
During his time at University of Arizona, Christopher evaluated the impact of vertical and horizontal airflow to prevent tipburn in lettuce crop grown in a vertical farming system. His research demonstrated that vertical airflow compared to horizontal airflow was more effective reducing aerodynamic resistance with improved airflow and transpiration, thus preventing tipburn in lettuce.
Indoor lighting to increase lettuce quality and nutrition
Nathan Kelly received his PhD from Michigan State University in 2023, under the advisement of Dr. Erik Runkle.
He investigated how light quality and quantity can be manipulated to elicit desired quality traits of lettuce grown indoors. He is also interested in how lighting can be used to promote pigment accumulation and the biosynthesis of nutritious secondary metabolites and vitamins.
Gio Papio is a former MS student who graduated from the Ohio State University in 2021 while under the advisement of Dr. Chieri Kubota.
During his time at Ohio State, Gio worked on developing a simple tool to analyze plant microclimate with regard to potential plant transpiration rates, as part of the effort to develop a simple methodology for growers to assess risks of tipburn incidence in lettuce. This tool is also useful for indoor HVAC design and optimization.
Enhanced environmental control and resource use in indoor farming
KC Shasteen was a MS student who graduated from the University of Arizona in 2022, under the advisement of Dr. Murat Kacira.
KC was working on modelling and computer vision-based crop biomass production predictions and co-optimization of environmental variables for enhanced environmental control and resource use in indoor vertical farming.
