Pay for faculty members at QU is NOT based on nationality. (The only exception is for Qataris, they get paid more.) There is a range of pay for a given position within a given department. If you get an offer, you can always negotiate for a higher salary if you think they really want you. On their side they are limited to salaries within the allowable range for the position/department and based on your experience.

I don't know the salary ranges for pharmacy or medicine.
