Department of Mathematical Sciences

Colleges and Faculties > Independent Faculties > Faculty of Science > Department of Mathematical Sciences

The Department of Mathematical Sciences is one of the foundational departments in the Faculty of Science, dedicated to excellence in teaching, research, and service. It offers rigorous training in pure and applied mathematics, statistics, computer science, and operations research.
Academic Programmes. The department offers undergraduate and postgraduate programmes designed to equip students with both theoretical knowledge and practical skills in:

  • Pure Mathematics (Algebra, Analysis, Geometry, Topology)
  • Applied Mathematics (Fluid Dynamics, Computational Mathematics, Biomathematics, Operations Research)
  • Industrial Mathematics
  • Statistics and Probability Theory
  • Computer Science and Numerical Methods

Vision Statement

The mathematics programme has a vision of enabling students develop the capability to provide solution to physical, chemical and biological problems.
To train students who enroll for the undergraduate programme to acquire a broad awareness in training high-level manpower to tackle the problem posed by the current challenges towards globalization, industrialisation, and information technology.

Our History

The department was founded in 1982. It has the responsibility for the provision of training needs and services in mathematics, statistics and computer science.
The mathematics and statistics programmes were the first to start. Other programmes commenced later, which included computer science and a combination of mathematics with computer science and statistics. Also, computer science with a combination of any of the following, namely economics, business administration and accounting.
The programmes were five years in duration, which involved four years of instruction and one year for industrial attachment.
A one-year Diploma Programme in Data Processing was also started in 1985 to meet the middle-level manpower needs of computer installations in industry and government. The department had so far offered degrees in computer science, mathematics and statistics.
In 1995, the Diploma in Data Processing (DDP) was extended to involve part-time students, and also introduced is a one-year Diploma in Computer Studies (DCS) meant for professionals in the computer industry.
Currently, the combined honours degree programmes with social/management courses are gradually being phased out and replaced with single honours programmes in mathematics, statistics and computer science. Only the five-year Computer Science degree programme has also been replaced with a four-year programme, as depicted in the student handbook prepared by the department.

Our Philosophy

The philosophy that guides the training of students in this department is the production of skilled manpower that is adequately furnished with the comprehensive information on technological development in an environment characterised by scarcely qualified mathematics, statistics and computer science teachers (relative to the growing population) and vast and rapidly increasing material resources, but with very weak data production and information management systems.

Such knowledgeable professional manpower has to be produced in an atmosphere with qualified and competent human and appropriate material resources using effective techniques of instruction. Consequently, the department provides opportunities for training, for the acquisition of basic and later higher degrees in the mathematical sciences.

The training programmes are mounted through classroom theoretical and tutorial instruction, laboratory practicals and industrial work experiences.

The department intends to nurture graduates who, by leveraging their sound foundational training and skills in the mathematical sciences, would become globally relevant in the industrial and academic domains and eventually emerge as future leaders in the fields of computing, mathematics, statistics and information and communication technology, both in Nigeria and the global community.

The department is committed to producing highly creative and innovative graduates that are competent enough to be self-employed in the field of mathematics, statistics, computer science and its allied disciplines, or at the very least be immediately employable.

Our Objectives

  1. To produce qualified teachers of the three components of mathematical sciences (mathematics, statistics and computer science) at both secondary and tertiary levels. This will reduce or eliminate the use of graduates from non-mathematical disciplines in teaching these subjects. 
  2. To produce competent Statisticians, Industrial Mathematicians and Computer Scientists to work in government, industry, research institutes and non-governmental organisations.
  3. To service other departments in the teaching of mathematics, statistics and computer science.
  4. To engage in research in the field of mathematical sciences to advance the frontiers of knowledge in the disciplines.
  5. Improve the effectiveness of the knowledge and skills of the products of the system.
  6. To render consultancy services in relevant areas to the university, government and private sector.

Dr. Sefiu Adekunle Onitilo is a Senior Lecturer and researcher in Applied Mathematics with expertise in Differential Equations, Fluid Dynamics, Computational Mathematics, Magnetohydrodynamics, and Mathematical Modeling of Biological and Epidemiological Systems. He obtained his Ph.D. in Mathematics in 2018 from Olabisi Onabanjo University, where his doctoral research provided significant insights into the Mathematical modeling of blood flow through a stenosed human carotid artery. He is currently serving as the Acting Head of Department of Mathematical Sciences, Olabisi Onabanjo University, Ago-Iwoye, Ogun State, Nigeria.

Research Focus

Dr. Onitilo’s research focuses on the application of advanced Mathematical methods to real-world challenges. His contributions span:

  • Mathematical Modeling of Biological Systems – including blood flow dynamics, infectious diseases such as COVID-19, pneumonia-meningitis co-infections, and cholera.
  • Fluid Dynamics and Magnetohydrodynamics (MHD) – investigating heat and mass transfer in porous media, oscillatory flows, and the effects of viscosity, radiation, and conductivity.
  • Computational Mathematics – applying analytical and numerical methods to complex physical and biological systems.

He has published extensively in national and international journals, including works in the Journal of the Nigerian Association of Mathematical Physics, Ife Journal of Science and Technology, Iraqi Journal of Science, African Journal of Science and Nature, and Cankaya University Journal of Science and Engineering.
