Three years later, the College of Engineering was established. By then, the number of enrolled students was 2,600. This was followed by the establishment of the College of Business & Economics in 1985. The new colleges prompted a large expansion of the university campus, which was overseen by Aga Khan Award for Architecture recipient Kamal El Kafrawi. By Fall Semester 2005 / 2006, the number of registrants for study at Qatar University had reached 7660 male and female students, equaling almost 1/6 of the eligible Qatari population.
