Short Profile

Dr. Agwuegbo, Samuel Obi-Nnamdi is an Associate Professor of Statistics at the Federal University of Agriculture, Abeokuta (FUNAAB). He served as Acting Head of the Department of Statistics from 2011-2015. Dr. Agwuegbo teaches courses in statistics at both undergraduate and postgraduate levels. He has supervised many undergraduates and postgraduate students’ projects and theses. During his tenure as the H.O.D, he was able to sustain full NUC accreditation status attained by the department.

Dr. Agwuegbo has published more than thirty (30) journal articles in stochastic processes, Time series and Multivariate Analysis and his research focus is on modelling complex behaviour of large dimensional state space in the field of economics, insurance and finance. As part of his efforts towards improving the quality of graduates of Statistics from the Department of Statistics, FUNAAB, he successfully introduced and sustained the use of softwares into teaching of Statistics courses at both undergraduates and Postgraduates levels. This effort has immensely helped to reposition the students towards acquisition of practical skills in data analysis and by extension preparing them for future challenges after graduation.

Dr. Agwuegbo is a member of the Nigerian Statistical Association (NSA), International Biometric Society (IBS) and American Statistical Association (ASA). He has attended both local and international conferences.
