You can update your name in myJH.

In myJH search for and click myProfile. This will open a page where you can update your name. It may take up to 24 hours for these updates to reflect in the system.

This change will be reflected in your library account on Catalyst, Interlibrary Loan Services, as well as other services that connect to your JHED ID.

For more information about updating your name see Chosen Name at JHU.
