Dr. (Mrs.) Wale-Orojo, Oluwaseun A. is currently a lecturer at the Department of Statistics, Federal University of Agriculture Abeokuta (FUNAAB), Ogun State, Nigeria. She got her Ph.D. (Statistics) at the Federal University of Agriculture Abeokuta (FUNAAB), Ogun State of Nigeria on “Modelling Rare Events in an Adaptive Cluster Sampling Design with Heterogeneity among Networks and Within the Network Units”. She has been involved in teaching Statistics courses and supervising undergraduate and postgraduate students.

Her major interest is in sampling techniques, this she has demonstrated with some of her publications, in the area of Sample Survey, Experimental Design, Statistical Inference with its Applications in modelling rare event. She has publications and referred conference proceeding to her credit. https://scholar.google.com/citations?hl=en&user=ma_QcQAAAAJ

Dr. (Mrs). Wale-Orojo has received grants to attend international training workshops and has presented papers at conferences. She has also attended workshops, seminars and short courses that have enhanced and broadened her teaching and research capabilities.
