Biomedical expert witnesses may write reports and testify on biomedical engineering, biomedical physics, and biotechnology, among other topics. On their website, the Biomedical Engineering Society describes bioengineering:
Bioengineering integrates physical, chemical, or mathematical sciences and engineering principles for the study of biology, medicine, behavior, or health. It advances fundamental concepts, creates for the molecular to the organ systems levels, and develops innovative biologics, materials, processes, implants, devices, and informatics approaches for the prevention, diagnosis, and treatment of disease, for patient rehabilitation, and for improving health[iii].
Generally, bioengineering encompasses other engineering disciplines when they are applied to living organisms (e.g. prosthetics in mechanical engineering). Bioengineering is often synonymous with biomedical engineering, though in the strict sense the term can be applied more broadly to include food engineering and agricultural engineering. Biotechnology also falls under the purview of the broad umbrella of bioengineering. Biological Engineering is the same thing as Agricultural Engineering, whereas Biomedical engineering (also known as bioengineering) is related with the medical field. Biological engineering is called Bioengineering by some colleges and Biomedical engineering is called Bioengineering by others.
