Certain publications are being imported from other repositories, but the RG team does not have the capacity to add millions of publications by hand. Users are expected to add missing publications themselves. See this help page ("How to add research") for detailed instructions how to add published or unpublished research to ResearchGate: https://help.researchgate.net/hc/en-us/articles/14293005132305. Before doing that, check whether there are publications by you not yet attached to your profile. There are at least two possibilities to find these:

1. Look at https://www.researchgate.net/profile/Clifford-Ugorji-2/unconfirmed (visible only for you)

2. Search for the titles of your missing publications at https://www.researchgate.net/search.Search.html?query=&type=publication

Then confirm authorship to attach these to your profile - see https://help.researchgate.net/hc/en-us/articles/14292798510993 for instructions.

Thank you
