North Carolina State University

What you'll study

The PhD programme emphasises original research supported by advanced coursework in engineering fundamentals and agricultural applications. Typical taught topics include:

• Advanced fluid mechanics and transport processes applied to soil, water and biological systems.
• Soil and water engineering, including irrigation, drainage, watershed hydrology and erosion control.
• Precision agriculture and sensing, covering GPS/GNSS systems, remote sensing, proximal sensing, and data analytics for field-scale decision support.
• Bioresource and bioprocess engineering for post-harvest handling, bioconversion and value-added processing.
• Environmental systems modelling and numerical methods for simulation of agroecosystems and transport of contaminants.
• Control systems and automation for agricultural machinery, greenhouse/controlled-environment systems and robotics.
• Experimental design and statistics tailored to agricultural research and field trials.

Students normally complete a combination of coursework and research credits, pass a qualifying or comprehensive examination, present and defend a doctoral research proposal, and write and defend a dissertation based on original research. Interdisciplinary projects are common and may involve collaboration with faculty in plant sciences, biological engineering, civil engineering, statistics, and computer science. Graduate teaching or research assistantships are typically part of the training experience.

Entry requirements

Applicants should hold a relevant bachelor's or master’s degree in agricultural engineering, biological engineering, civil engineering, mechanical engineering, biosystems engineering, or a closely related science or engineering discipline. Typical admissions expectations include:

• Academic preparation: strong undergraduate performance in core engineering and science courses (mechanics, thermodynamics, calculus, physics, chemistry, and introductory soil/biological/chemical engineering as appropriate).
• Research experience: previous research projects, a master’s thesis, or substantial laboratory/field experience is highly valued and often expected for direct entry to a PhD.
• Application materials: academic transcripts, a statement of research interests, CV, and at least two or three academic or professional references that can comment on research potential.
• English language proficiency: for international applicants, evidence of English proficiency is required (test scores or other institutionally accepted evidence) unless exempted by university policy.

Standardised test requirements (such as the GRE) may vary by year or by department practice; applicants should check the department’s graduate admissions guidance for current expectations. Admission is competitive and often linked to availability of faculty willing to supervise the proposed research and to funding availability.

Career prospects

Graduates with a PhD in Agricultural Engineering pursue diverse careers across academia, government, and industry. Common pathways include:

• Academic and research careers: faculty positions in engineering and agricultural colleges, or research scientist roles at universities and research institutes.
• Government and public sector: technical and policy roles at national agricultural agencies, environmental and natural resources agencies, and international development organisations.
• Industry: R&D, product development, and technical leadership in agricultural equipment manufacturers, precision-ag tech firms, food and bioprocessing companies, and environmental consulting firms.
• Start-ups and entrepreneurship: commercialising sensor platforms, automation solutions, or sustainable processing technologies.
• Extension and outreach: positions focused on translating research into practice through extension services and industry partnerships.

Why study at North Carolina State University
