So, I had a few minutes' fun looking up on how much of a scam this "university" is. It is nothing more than a diploma mill. I hope these few tips may serve as useful warning signs for other dodgy institutions. From the university's website:
Duration of the Program
The normal duration of the PhD program for full-time students is 6
semesters (24 months). Course work of 18 semester hours may normally
be completed in three semesters (12 months). The dissertation may be
completed in the remaining 3 semesters (12 months).
No PhD program is that short.
Additionally, any "university" whose website does not have a list of its departments and academic staff should be treated with great suspicion. I can find no information anywhere about its research departments or staff.
This is what the address of the place looks like on Google Street View (401 Kamakee Street #312, Honolulu, used to be the home of the "Apeautique medical spa"):
This is a diploma mill. Any institution capable of awarding a bona fide PhD degree must have a proper campus with sufficiently qualified and reputable academic staff (especially when they claim to award PhDs in civil engineering).
