Can a Staff Scientist Get a Sabbatical

No. Sabbatical leave is not part of the staff scientist's terms of employment.

That being said, starting in 2022, the Research Grants & Projects Office started a new initiative whereby staff scientists can apply for a long-term (up to 3 months) travel grant to “to explore collaborations and acquire expertise in cutting edge technologies” (per the grant description). Application deadlines are Feb. 1, 2022, and Aug. 1, 2022 (two submissions). For details, see the RGP call here.
