# Changing the active researcher

Only one researcher can serve as the operator of the Kernel Flow system for the purpose of configuring and recording datasets. The ID of the active researcher is embedded in the metadata recorded along with the datasets.

Additionally, researchers may only collect data for studies in which they are authorized. For these reasons, it’s important that the correct researcher is logged into the Kernel Portal whenever a dataset is recorded.
