Here are some choices:
1. Biologist
- Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies--human medical research, plant research, animal research, environmental system research--at the cellular level or the ecosystem level or anywhere in between.
2. Scientist
A scientist is a person who conducts scientific research to advance knowledge in an area of interest. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science.
3. Microbiologist
Microbiologists investigate the vital role of microbes in soil. Some concentrate on plant pests and diseases, developing ways to control them or even use microbes to control insect pests and weeds. Others research the microbes that cause diseases in farm animals.
4. Laboratory Technician
Clinical laboratory technologists and technicians collect samples and perform tests to analyze body fluids, tissue, and other substances. Many clinical laboratory technologists and technicians work in hospitals. Others work in medical and diagnostic laboratories or doctors' offices.
5. Biochemist
Biochemists and biophysicists study the chemical and physical principles of living things and of biological processes, such as cell development, growth, heredity, and disease.
6. Environmental Scientist
Environmental scientists use their knowledge of the natural sciences to protect the environment. Environmental scientists and specialists use their knowledge of the natural sciences to protect the environment and human health. They may clean up polluted areas, advise policymakers, or work with industry to reduce waste.
7. Marine Biologist
Marine biologists study biological oceanography and the associated fields of chemical, physical, and geological oceanography to understand marine organisms. Marine biology is a very broad area, so most researchers select a particular area of interest and specialize in it.
8. Geneticist
A scientist who has special training in the study of genes and heredity (the passing of genetic information from parents to their children). A medical geneticist is a doctor who specializes in diagnosing and treating genetic disorders or conditions.
9. Pharmacist
Pharmacists are healthcare professionals who specialize in the right way to use, store, preserve, and provide medicine. They can guide you on how to use medications, and let you know about any potential adverse effects of what you take. They fill prescriptions issued by doctors and other healthcare professionals.
10. Nurse Practitioner
A nurse practitioner (NP) is a nurse with a graduate degree in advanced practice nursing. This type of provider may also be referred to as an ARNP (Advanced Registered Nurse Practitioner) or APRN (Advanced Practice Registered Nurse). Types of health care providers is a related topic.
