Dr. Leigh Whittinghill is a horticulturalist with expertise in vegetable production and green roofs. Her research focuses on urban agriculture, novel production systems that could help increase production area and reduce costs, and the potential environmental impacts of urban agricultural practices.

Ph.D. Michigan State University (Horticulture) 2012  
B.A. Middlebury College (Biology) 2006

Station Career:
Assistant Agricultural Scientist II, Department of Forestry and Horticulture, 2021-present

Past Research:
Dr. Whittinghill’s doctorate research at Michigan State University focused on the use of green roof systems for food production, examining both crop yields and the potential impact that crop production could have on the known benefits of green roofs. As a Postdoctoral Fellow at The Earth Institute at Columbia University, she helped to examine impact of a full-scale rooftop farm on green roof runoff water quality and quantity. At Kentucky State University, Dr. Whittinghill expanded this research to include the examination of runoff water quality from ground level container and raised beds systems as well. She also examined the production of several high value crops in these systems including several varieties of greens and saffron.  

Current Research:
Dr. Whittinghill’s current research at CAES will continue to examine urban food production practices to increase food production, decrease environmental impact, and find solutions to urban food production problems.
