The impact of mathematics research on society is significant and far-reaching, resulting in many scientific and technological breakthroughs. Developments in physics, chemistry, computer science, and engineering heavily rely on mathematical principles and models. Without the continuous advancement of mathematical research, the modern technological world would be impossible. Recently, Postdoctoral Research Fellow (PRF), Dr Ahmed Audu joined Sefako Makgatho Health Sciences University (SMU) to develop his career as an academic researcher in mathematical statistics under the supervision of Professor Maggie Aphane, Head of Department: Mathematics and Applied Mathematics. His fellowship is funded by the Tertiary Education Trust Fund (TETFUND), a Nigerian government agency.
Dr Audu’s educational qualifications entail a Doctor of Philosophy in Statistics (University of Ilorin, Nigeria); Master of Science and Bachelor of Science in Statistics (Usmanu Danfodiyo University, Nigeria); Professional Diploma in Education (Ahmadu Bello University, Nigeria); and National Diploma in Statistics (Niger State Polytechnic Zungeru, Nigeria). He is a seasoned academic with extensive work experience as a Senior Lecturer, Lecturer, Assistant Lecturer, and Graduate Assistant at Usmanu Danfodiyo University.
His responsibilities include collaborating with other researchers. He is expected to publish, at least, five articles in the accredited Institute for Scientific Information (ISI) journal and work closely with principal investigators, professors, and other research staff members. This allows him to learn new techniques and approaches from more experienced researchers.
“Mathematical research leads to the development of tools and techniques that can be applied to solve complex real- world problems. These include areas such as weather prediction, cryptography, and virus modelling. The study of mathematics trains individuals to think logically, analyse problems systematically, and develop effective solutions. These skills are invaluable in many aspects of life, from personal finance to complex decision-making,” explains Dr Audu.
Understanding and applying mathematical concepts empowers individuals to engage meaningfully in discussions and initiatives that address global challenges, such as climate change, sustainable development, and data- driven decision-making. Dr Audu’s areas of research interest are mathematical and applied statistics. He specializes in mathematical statistics, sampling theories and survey methods to be specific.
A solid foundation in mathematical statistics is essential for pursuing postgraduate studies in fields like econometrics, biostatistics, machine learning, and operations research. The analytical and quantitative skills developed during the study of mathematical statistics provide a strong foundation for further academic and professional development. His current students at SMU have a mathematics background with little exposure to statistics. As a result, he organised a series of lectures and presentations with them to bridge the missing gaps and he was overwhelmed with the speed of their understanding.
“I am currently supervising some postgraduate students in the department of mathematics in collaboration with some staff members of mathematics and statistics. I am training them in mathematical statistics especially sampling theory and survey methods. This will complement and enhance the existing research programmes at the university. The results of the interactions will also lead to discoveries, publications, and advancements in the field” enlightens Dr Audu.
Dr Audu said Postdoctoral Research Fellow (PRF), experience will lead to mentorship and guidance, development of new skills and techniques, enhanced publication record, networking and collaborations and exposure to diverse research environments. This is what motivated him to join SMU. He said the ranking of SMU among its peers in Africa and globally motivated him. “I am not a mathematician, but a statistician. Nevertheless, statistics is a subset of mathematics. So, I love mathematics. I found it easier to understand its concepts. I see logical thinking and problem-solving skills required in mathematics as an enjoyable mental exercise. The goal of any academician is to attain the apex rank of the career and I’m not an exception. But my focus now is career development through experiences and collaborations,” he concluded.
