@yvonnefroehlich Thanks for the update. Do you also want to update the affiliation in CITATION.cff and in the Zenodo record for consistency. If so, I suggest keeping this PR open until we're ready to release v0.16.0, otherwise we may forget to update CITATION.cff/Zenodo when making the release.

Will merge when releasing v0.16.0.
