The mission of PhD program is to produce innovative leaders in the field of mathematics who will be able to integrate the roles of researchers, educators and intellectual leaders by conducting original, relevant and rigorous research in the field of mathematics in accordance with national and international demands.

• PEO-1: serve highly consequential functions in society, including the fields of teaching and social impact-based research, in view of national and international demands.
• PEO-2: become effective members of computing related organizations for the design of algorithms and their implementations in computational sciences and applied sciences related to modern industry.
• PEO-3: become effective members of national and international R & D organizations working in interdisciplinary fields of mathematics and engineering where they can formulate, analyze, evaluate, validate, and extract scientific conclusions.
• PEO-4: enhance their critical thinking and mathematical skills, holding ethical values, such that they can analyze data and interpret it for revealing the facts about physical happenings and contribute to the community as a responsible person.
