How to Become a Medical Scientist
Medical scientists typically have a Ph.D. and sometimes are certified medical doctors as well.
Medical scientists typically have a Ph.D., usually in biology or a related life science. Some medical scientists get a medical degree instead of, or in addition to, a Ph.D.
Medical scientists typically need a Ph.D. or medical degree. Applicants to either of these programs typically need a bachelor's degree in biology, chemistry, or a related field. Undergraduate students benefit from taking a broad range of classes, including life sciences, physical sciences, and math. Students also typically take courses that develop communication and writing skills, because they must learn to write grants effectively and publish their research findings.
After students have completed their undergraduate studies, they typically enter Ph.D. programs. Dual-degree programs are available that pair a Ph.D. with a range of specialized medical degrees. A few degree programs that are commonly paired with Ph.D. studies are Medical Doctor (M.D.), Doctor of Dental Surgery (D.D.S.), Doctor of Dental Medicine (D.M.D.), Doctor of Osteopathic Medicine (D.O.), and advanced nursing degrees. Whereas Ph.D. studies focus on research methods, such as project design and data interpretation, students in dual-degree programs learn both the clinical skills needed to be a physician and the research skills needed to be a scientist.
Graduate programs emphasize both laboratory work and original research. These programs offer prospective medical scientists the opportunity to develop their experiments and, sometimes, to supervise undergraduates. Ph.D. programs culminate in a dissertation that the candidate presents before a committee of professors. Students may specialize in a particular field, such as gerontology, neurology, or cancer.
Those who go to medical school spend most of the first 2 years in labs and classrooms, taking courses such as anatomy, biochemistry, physiology, pharmacology, psychology, microbiology, pathology, medical ethics, and medical law. They also learn how to record medical histories, examine patients, and diagnose illnesses. They may be required to participate in residency programs, meeting the same requirements that physicians and surgeons have to fulfill.
Medical scientists often continue their education with postdoctoral work. This provides additional and more independent lab experience, including experience in specific processes and techniques, such as gene splicing. Often, that experience is transferable to other research projects.
Licenses, Certifications, and Registrations
Medical scientists primarily conduct research and typically do not need licenses or certifications. However, those who administer drugs or gene therapy or who otherwise practice medicine on patients in clinical trials or a private practice need a license to practice as a physician.
Medical scientists often begin their careers in temporary postdoctoral research positions or in medical residency. During their postdoctoral appointments, they work with experienced scientists as they continue to learn about their specialties or develop a broader understanding of related areas of research. Graduates of M.D. or D.O. programs may enter a residency program in their specialty of interest. A residency usually takes place in a hospital and varies in duration, generally lasting from 3 to 7 years, depending on the specialty. Some fellowships exist that train medical practitioners in research skills. These may take place before or after residency.
Postdoctoral positions frequently offer the opportunity to publish research findings. A solid record of published research is essential to getting a permanent college or university faculty position.
Work Experience in a Related Occupation
Although it is not a requirement for entry, many medical scientists become interested in research after working as a physician or surgeon, or in another medical profession, such as dentist.
Communication skills. Communication is critical, because medical scientists must be able to explain their conclusions. In addition, medical scientists write grant proposals, because grants often are required to fund their research.
Critical-thinking skills. Medical scientists must use their expertise to determine the best method for solving a specific research question.
Data-analysis skills. Medical scientists use statistical techniques, so that they can properly quantify and analyze health research questions.
Decisionmaking skills. Medical scientists must determine what research questions to ask, how best to investigate the questions, and what data will best answer the questions.
Observation skills. Medical scientists conduct experiments that require precise observation of samples and other health-related data. Any mistake could lead to inconclusive or misleading results.
