Science and the Medical field have many ways of working. 
Here are some examples:

• Research Scientist: Conduct experiments, analyze data, and publish research results in fields such as biology, chemistry, physics, or environmental science. 

• Medical Doctor (MD): Diagnosis and treatment of diseases, injuries, and other health conditions, especially in fields such as pediatrics, cardiology, oncology, or neurology. 

• Registered Nurse (RN): Provides patient care, administers medications, and provides medical assistance in hospitals, clinics, or other health care settings. 

• Pharmacist: Dispenses medications, provides prescribing information to patients and physicians, and ensures the safe and effective use of medications. 

• Biomedical Engineer: Designs and develops medical devices, prosthetics, and other medical technologies to improve patient outcomes and outcomes. 

• Clinical Trial Coordinator: Administer clinical trials, recruit participants, collect data, and ensure compliance. 

• Medical Laboratory Scientist: Performs laboratory tests on patient samples to help diagnose and treat diseases, such as blood tests or microbial infections. 

• Healthcare Manager: Oversees the operations of a hospital, hospital, or healthcare facility, including budgeting, operations, and strategic planning. 

• Bioinformatician: Use computational tools and techniques to analyze biological data to study genetics, genomics, and other areas of molecular biology. 

• Physician (PA): Provides basic healthcare services, including medical exams, diagnoses, and prescription medications, under the supervision of a licensed physician. 

The study of science and medicine each has its specific role and opportunity for advancement.
