Yes, of course professors would have their own profile; like I said it would resemble Match.com with both parties making their own profiles. I came up with the idea for the same reason mentioned by @Islamahmed, because faculty research is difficult to access particularly for those without the resources to get academic journals or access to JStor.
Another reason the app might be useful is to cut out all of the inefficiencies involved in the process. For example, faculty have told me of the many useless emails they get from students that are not a right fit; wouldn't it be helpful to have an app to narrow the search focus, and dispose of all this waste? And yes @TakeruK the whole point of the site is to match research interests, but additionally to match personalities. It does no good to have common interests if there is no chemistry. Again, it's about EFFICIENCY.
I agree that faculty would need incentive to join. The appeal of reducing waste might entice, but that would depend on participation. That is why your feedback is so crucial, so thank you for your input, and please keep adding!
