Principal Scientist Position Descriptions

Principal scientists manage and oversee scientific research teams.

Moving from the Bunsen burners of high school chemistry to high-tech, multi-million dollar laboratories, scientists take a love for science and apply it to a career. A principal scientist works in all different types of industries including agriculture, food, environment, medical, technology, life sciences and physical sciences. The number of female scientists varies depending on the industry, with women making up only 25 percent of environmental scientists but over 50 percent of medical scientists, according to the Bureau of Labor Statistics.

Medical and Health Sciences

Principal scientists in the medical and health sciences can serve in a variety of sub-specialties, ranging from pharmacology to toxicology to histology. The exact duties depend on the type of science she’s studying, but general job duties include studying the causes of human diseases and developing cures and treatments for diseases. As a medical principal scientist, you may also study current drugs to make them more effective or create new medications. Other job duties include writing grant proposals, applying for funding, training other scientists and maintaining a clean and sterile lab environment.

Agriculture and Food Sciences

In the agricultural and food sciences, principal scientists still work in a lab setting performing research but the subject matter changes to food and crops. Principal agricultural scientists try to improve crop and farm animal output by developing hybrids and new methods of growing crops and raising animals. In the food industry, a principal scientist comes up with new food products, as well as ways to create, package and ship them. In agriculture and food, there's typically more travel time, visiting farms and food factories to do hands-on projects at those facilities. As the lead scientist, you’ll also be responsible for staying up-to-date on the laws that regulate your industry and assure your company adheres to the rules.

Technology and Information Sciences

As a principal scientist in the technology and information sciences, you’ll analyze the ways people use technology and attempt to improve on those methods. You’ll solve complex computer issues, invent new computer languages and create software systems. Often, you’ll publish your research findings and write papers and reports on the experiments you conduct and the technology you develop. Because technology research comes at a large price tag, you’ll help develop research budgets and make sure teams stick to them as best as possible.

Physical and Life Sciences

Another major area where a principal scientist does research and development is in the physical and life sciences. The physical and life sciences include areas like chemistry, biology, environmental and conversation. Job duties for physical and life principal scientists are similar to those for other scientists and include research projects, experiments and report finding. You’ll also have responsibilities specific to your field. For example, as an environmental principal scientist you’ll collect and analyze soil, air and water samples, looking for problems and coming up with solutions to fix those issues.
