The SFI Profile page displays current eGC1s on which you are named. If you wish to add older eGC1s to your current list of sponsored research, click the "Can't see your eGC1?" link on your SFI Profile page. The Additional Sponsored Research page will display eGC1s which are not as current or where you are being paid on the budget but are not named on the eGC1.
In addition, if you feel you should be added to an eGC1 that's not listed on this page, use the Request Access feature.
