Biological Engineering is a science-based engineering discipline that integrates engineering and biological sciences in one curriculum. Biological engineers develop products and design systems or processes for improved human health, use of bio-resources, and protection of the environment. The three career emphasis areas include:
• Biomedical Engineering provides health care advances throughs
Medical processes.
Disease diagnosis and treatment.
Patient rehabilitation.
• Bioprocess Engineering facilitates value-added products and food safety through:
Innovative technological use of renewable biological materials.
Enhanced packaging, quality and distribution of bio-products.
• Bioenvironmental Engineering provides advances in environmental protection through:
Water and air quality systems.
Advanced conservation techniques.
