Dr. Jonathan Egilla is an Assistant Professor, and Research Principal Investigator with the Lincoln University Cooperative Research Programs, he has teaching assignments in the Department of Agricultural & Environmental Sciences.  His research involves advances in soilless crop culture in controlled environment systems.  Phase one of the research project involved development of ‘sustainable small-scale hydroponic cropping of specialty vegetables and herbs for limited resource growers,’ and focused on the screening of various vegetables, culinary and medicinal herbs, and the evaluation of commercial fertilizers as sources of mineral nutrition for hydroponic production. The current and second phase of his research project involves ‘soilless substrate evaluation and nutrient management in sustainable small-scale hydroponic production.’  He has been working with small-scale farmers throughout Missouri to develop sustainable hydroponic and aquaponic production systems.  He has submitted grant proposals to the North Central Region Sustainable Research and Education (NCR-SARE) program, and other agencies for funding.  He has published several scientific papers in various areas of crop physiology including his current work in hydroponic research.  He is an active member of the American Society for Horticultural Science. He was appointed to the AMS-USDA “Plant Variety Protection” Board in January 2011.
