Question: Which of the univerisities where Cioculescu held teaching positions in Romanian literature has the highest student enrollment? Passage:Serban Cioculescu (; 7 September 1902 25 June 1988) was a Romanian literary critic, literary historian and columnist, who held teaching positions in Romanian literature at the University of Iasi and the University of Bucharest, as well as membership of the Romanian Academy and chairmanship of its Library. Often described as one of the most representative Romanian critics of the interwar period, he took part in the cultural debates of the age, and, as a left-wing sympathizer who supported secularism, was involved in extended polemics with the traditionalist, far right and nationalist press venues. From early on in his career, Cioculescu was also noted for his selective approach to literary modernism and the avant-garde, preferring to place his cultural references with Neoclassicism.
