The phrase "one's original research" refers to a person's own investigative work, conducted in order to discover new information or knowledge. This type of research is typically done by an individual or team of individuals who design and conduct their own experiments, surveys, observations, or other data collection methods to answer specific questions or test hypotheses. The goal of original research is often to contribute new findings or perspectives to a particular field of study, which can then be built upon by others in the future.
