Food Science and Nutrition
The Food Science and Nutrition programme from Illinois Institute of Technology is awarded in recognition of mastery in food science and nutrition, and upon demonstration of an ability to make substantial creative contributions to the advancement in knowledge in food safety, food science, or nutrition.

Marine, Estuarine and Environmental Sciences
The goal of the Marine Estuarine Environmental Sciences course at University of Maryland, Baltimore County (UMBC) is to train students with career interests in some aspect of environmental science involving terrestrial, freshwater, marine, or estuarine systems and leads to both the Ph.D. and M.S. degrees.
Ocean Sciences - Marine Biogeochemistry
The mission of the Ocean Sciences - Marine Biogeochemistry graduate program at the University of Miami is to provide our students with specialized knowledge in important ocean science sub-disciplines as well as a broad understanding of the ocean as a key component of the Earth System.
Horticultural Biology
Although emphasis is on horticultural plants and systems commonly found in areas of temperate climate, graduate study on species and cropping systems of tropical areas is also possible by use of our extensive greenhouse and growth chamber facilities, and through conduct of thesis research in tropical areas. The Horticultural Biology program is offered by Cornell University.
Agronomy
Incoming Agronomy students at Kansas State University , commonly have a Bachelor of Science degree in agriculture, agronomy, crop science, soil science, or a related life science. The most important considerations for applicants are an interest in continued study and intensive research in a specific area of agronomy along with minimum prerequisites for admission to the program.
Horticulture
The Horticulture program offered by Colorado State University develops a horticulture graduate student into a professional horticulturist on the highest plane.
Forestry and Natural Resources
In the Forestry and Natural Resources phd degree at University of Georgia we prepare leaders in the conservation and sustainable management of forests and other natural resources; to discover ways to restore and better use the earth’s natural resources; and to put into practice forestry and natural resources knowledge.
Biosystems and Agricultural Engineering
Biosystems engineers are trained in biological, environmental, and engineering sciences and challenged to improve the sustainability of production systems, decrease or eliminate environmental hazards, and preserve natural resources. We offer a Biosystems and Agricultural Engineering degree at the University of Kentucky.
Animal Sciences
Animal Sciences graduate students at Purdue University are expected to apply principles from biological, physical, and behavioral sciences to make discoveries that improve livestock production, enhance food quality and safety, and uncover molecular mechanisms that regulate animal physiology.
Environmental and Forest Sciences
The graduate Environmental and Forest Sciences degrees at University of Washington prepare students for careers in academia, education, public agencies, industry, the private sector and nonprofit organizations.
