Horticulture and Landscape Architecture 

  • Assistant Professor Controlled Environment Agriculture
Horticulture Room 109B
625 Agriculture Mall Dr.
West Lafayette, IN 47907

Dr. Nemali has responsibility for extension, research and teaching activities in the department. He specializes in the area of controlled environment agriculture, which includes vegetables and ornamentals grown in greenhouses and vertical farms using hydroponic production systems.  A primary goal of his program at Purdue is to develop new and affordable technologies that improve sustainability (increase productivity, reduce resource waste, minimize environmental impact, and increase profits) in controlled environment agriculture and train growers with new technology.  He teaches a course titled "Controlled Environment Production of Horticultural Crops".  He is passionate about actively engaging and contributing to the existing diversity programs at Purdue.
