Mathematics & Statistics Department, School of Arts & Sciences
Osho Ajayi holds a Ph.D. degree in Statistics from the University of Glasgow, United Kingdom, where he also held undergraduate class teaching and demonstration appointments while completing his degree. Before joining the American University of Nigeria, he held an academic research position at the University of Reading, England working on methods for efficiently estimating the recombination rate in a human population using candidate datasets. He thereafter worked as a Researcher Associate at the University of St-Andrews, St-Andrews, Scotland on developing and evaluating efficient statistical tests to understand the mechanics of the population divergence of Senecio, within the United Kingdom.
An enthusiast in the application of statistical knowledge in biomedical science and the related field of using microarray to identify genetics pathways in pathology, Osho was for several years a Research Statistician with the MRC-Biostatistics Unit/Institute of Public Health, University of Cambridge, Cambridge England. Prior to his Ph.D. degree, Osho served briefly as a member of the academic staff at the University of Ibadan, Ibadan, Nigeria before joining the International Institute of Insect Physiology and Ecology, Nairobi, Kenya as a Scholar.
Osho Ajayi currently chairs the Mathematics & Statistics Department at AUN in addition to his primary teaching responsibility. He currently teaches undergraduate introductory general Statistics and Non-parametric statistics classes but has over the past several years instructed a number of different Mathematics and Statistics courses to both undergraduate and graduate classes across the different schools at AUN. He serves on the dissertation committee of several graduate students in AUN’s School of Business and Entrepreneurship.
Osho is a member of professional bodies that include the American Statistical Association and has research interest in the general application of statistical methods to count data and the modeling of the underlying processes that generated such datasets, and the analysis of big data. His most recent published works include the one co-authored with another colleague in the department that was recently accepted for publication by the Journal Quality and Quantity.
