You may justify the reason for the project by given detail information on it using the Triangle of Benefit Approach: How is the project going to benefit people in the project area; How is it going to benefit the sponsor or sponsors and how it will Impact the world at large. After that you can contact Martha Contreras through the project sponsor or even Google her name if you know her institution and you can get her contacts.
Thank you, but I don't see any way to do all that in ResearchGate. Besides, it sounds like several hours of effort for a project in which I am only marginally interested.
