Agricultural and Biological Engineers apply fundamental engineering principles to problems relating to agriculture and biology. ABE students learn to design technological solutions to problems in agricultural, food, bioenergy, water, and other biological systems.
The Bachelor of Science in Agricultural and Biological Engineering (ABE) equips graduates to address grand challenges related to food, water, energy, and the environment. The program offers an ABET-accredited, flexible curriculum.
**The ABE program comprises six concentrations. Students pursuing this major select one of the following concentrations:**
- [Bioprocess Engineering and Industrial Biotechnology Concentration](https://catalog.illinois.edu/undergraduate/eng_aces/agricultural-biological-engineering-bs/bioprocess-engineering-industrial-biotechnology/)
- [Off-Highway Vehicle and Equipment Engineering Concentration](https://catalog.illinois.edu/undergraduate/eng_aces/agricultural-biological-engineering-bs/off-highway-vehicle-equipment-engineering/)
- [Renewable Energy Systems Engineering Concentration](https://catalog.illinois.edu/undergraduate/eng_aces/agricultural-biological-engineering-bs/renewable-energy-systems-engineering/)
- [Soil and Water Resources Engineering Concentration](https://catalog.illinois.edu/undergraduate/eng_aces/agricultural-biological-engineering-bs/soil-water-resources-engineering/)
- [Sustainable Ecological and Environmental Systems Engineering Concentration](https://catalog.illinois.edu/undergraduate/eng_aces/agricultural-biological-engineering-bs/sustainable-ecological-environmental-systems-engineering/)
- [Synthetic Biological Engineering Concentration](https://catalog.illinois.edu/undergraduate/eng_aces/agricultural-biological-engineering-bs/synthetic-biological-engineering/)
Each concentration (30 hours each) has its own unique body of knowledge and engineering tools and builds upon engineering fundamentals from the first two years of the program.
