Welcome to the Horticulture graduate program in the Department of Horticulture and Landscape Architecture at Purdue University. The Horticulture graduate program offers the thesis-based degrees of Doctor of Philosophy (Ph.D.) and Master of Science (M.S.), as well as a non-thesis degree, Master of Agriculture (M.Agr.). Reflecting the research interests of our faculty, graduate students in the Horticulture graduate program have projects that explore fundamental concepts of plant biology, applied aspects of horticulture, or that integrate basic plant science with field and contained environment studies. The goal of the Horticulture Graduate Program is to prepare students for professional careers in basic and applied plant science with an emphasis on improvement of food, fiber, fuel, and ornamental crops. The Horticulture research program in Purdue HLA is internationally recognized for the importance of its discoveries, extraordinary publication and extramural funding records, and the strong involvement of the faculty in graduate student programs. The program was very highly ranked in the latest National Research Council evaluation of plant biology programs. The Horticulture graduate faculty includes a member of the National Academy of Sciences, five distinguished professors, and four fellows of the American Association for the Advancement of Science. Most members of the faculty have served as program managers or panel members for extramural funding agencies. Many have served as officers of international and national scientific societies. A substantial component of the research in the program involves international programs. A majority of the research in the department is extramurally funded. Areas of concentration in the program include plant molecular genetics and epigenetics, plant physiology and stress biology, plant genetics and breeding, plant cellular and developmental biology, sustainable production horticulture, bioenergy, contained environment growing, floriculture, and horticultural marketing.
