Biomedical engineers work in a variety of settings, depending on what they do. Some work in hospitals where therapy occurs, and others work in laboratories doing research. Still others work in manufacturing settings where they design biomedical engineering products. Additionally, these engineers also work in commercial offices where they make or support business decisions. Biomedical engineers work with patients and in teams with other professionals. Thus, where and how they work are often determined by others’ specific needs. For example, a biomedical engineer who has developed a new device designed to help a person with a disability to walk again might have to spend hours in a hospital to determine whether the device works as planned. If the engineer finds a way to improve the device, the engineer might have to then return to the manufacturer to help alter the manufacturing process to improve the design.
