The mathematics department at SBASSE-LUMS has gained prominence for high-quality teaching, research, and activities related to the mathematical research and outreach it conducts. The department has over 12 faculty members working in diverse areas of pure, applied, and computational mathematics who provide rigorous training to our students. Standard courses also include instruction on applications and cutting-edge mathematical research. The department's research environment is enhanced by various seminars held virtually/physically every week, including the John Conway Spirited Seminar Series. Over the years, the department has been hosting regular workshops and thematic research schools. In recognition of the department’s ongoing endeavors, the European Mathematical Society (EMS) has awarded it the status of an Emerging Regional Center of Excellence (ERCE). As an ERCE bearer, the department has been organizing various activities to create opportunities for collaboration between students and researchers.

Another honor received by the mathematics department is its selection as an ICTP’s Affiliated Center by the Abdus Salam International Centre for Theoretical Physics (ICTP). As an ICTP's Affiliated Centre, the department hosts the prestigious International Mathematics Master program. This two-year program recruits top talent offers solid coursework and research and incorporates the involvement of the international math community through visiting professorships and joint research supervision. The Centre International de Mathématiques Pures et Appliquées (CIMPA) France selected the mathematics department at SBASSE-LUMS to host CIMPA Research School on Algebraic and Combinatorial Methods in Geometry in March 2022. Moreover, the department has been organizing several in-house outreach activities like LUMS Math Circles to popularize mathematics among school kids.
