Master’s and Ph.D. Programs
Welcome to the Horticulture and Landscape Architecture graduate program in the Department of Horticulture and Landscape Architecture at Purdue University. The HLA graduate program offers the thesis-based degrees of Doctor of Philosophy (Ph.D.) and Master of Science (M.S.), Master of Science in Landscape Systems and Design (M.S.). Reflecting the research interests of our faculty, graduate students in the HLA graduate program have projects that explore fundamental concepts of plant biology, applied aspects of horticulture and landscape architecture, or that integrate basic plant science with field and contained environment studies. The goal of the HLA Graduate Program is to prepare students for professional careers in landscape design, basic and applied plant science and their economics and marketing with an emphasis on the improvement of food, fiber, fuel, ornamental crops, horticultural economics/marketing, and other related topics.
