So the number of FTEs underestimates the number of people that actually are NASA employees, though probably not by much. These numbers do not include the many people who work for other companies but who work on NASA projects. Some of those people work at NASA centers doing jobs that are indistinguishable from the jobs of civil servants in the next cubicle. Others work at aerospace companies building hardware on contract to NASA.
Medical scientists research human diseases and conditions with the goal of improving human health. Most medical scientists conduct biomedical research and development to advance knowledge of life processes and of other living organisms that affect human health, including viruses, bacteria, and other infectious agents.
The specific activities of the biomedical scientist can differ in various parts of the world and vary with the level of education. Generally speaking, biomedical scientists conduct research in a laboratory setting, using living organisms as models to conduct experiments.hese scientists work to gain knowledge on the main principles of how the human body works and to find new ways to cure or treat disease by developing advanced diagnostic tools or new therapeutic strategies. The research of biomedical scientists is referred to as biomedical research.
