eksperimentatorius

Eksperimentatorius is a person who designs and conducts experiments to test hypotheses or develop technologies. They may work in academic laboratories, industrial research and development, or educational settings. The term is used for scientists, engineers, students, and citizen scientists alike.

The word stems from eksperimentas (experiment) with the Lithuanian-agent suffix -torius. The feminine form is eksperimentatorė. It is a neutral, standard term in scientific and educational contexts.

Typical activities include formulating hypotheses, designing procedures, selecting controls, collecting and analyzing data, and reporting results. An eksperimentatorius aims for methodological rigor, reproducibility, and clear communication of methods and findings.

Ethical and safety considerations are integral, covering informed consent for studies involving people, welfare of animals in research, data integrity, and compliance with institutional guidelines and regulations.

In Lithuanian texts, eksperimentatorius denotes a person who performs experiments rather than a fictional or sensational role; the English equivalent is experimenter. The term can describe professionals, students, or enthusiasts engaging in controlled investigations.
