About Astronomers

Research Scientists conduct original scientific investigation to advance knowledge or develop practical applications in fields ranging from biology and chemistry to materials science, physics, and computer science. In academic settings, they design experiments, collect and analyze data, develop and test hypotheses, and publish findings in peer-reviewed journals. In corporate or government research settings, the work is often more applied—translating scientific knowledge into new products, processes, or technologies with commercial or policy value. The research process demands rigorous experimental design, statistical analysis, and critical interpretation of results. Research scientists must command the existing literature in their field, position their work relative to prior knowledge, and communicate findings to both scientific and lay audiences. Collaboration with other scientists, technicians, and sometimes clinicians or engineers is standard, as is mentorship of graduate students or junior researchers. Securing research funding through competitive grant applications is a critical skill in academic research careers. A doctoral degree (PhD) is the standard entry-level credential for independent research positions.
