Dr. Chisimkwuo John, [BSc. (Umudike), BComHons, MCom (Stellenbosch) and Ph.D (Umudike)]
is a Senior Lecturer in the Department of Statistics, Michael Okpara University of Agriculture,
Umudike (MOUAU) since 2013. He is a major in the area of Applied Industrial Statistics and Data
Analytics where he obtained his Ph.D. He has taught both postgraduate and undergraduate modules
like the Multivariate Statistical Analysis, Statistical Computing using R/Python, Statistical Quality
Control, Design of Experiments, and some other service Statistics courses for several years. Dr.
John was the pioneer Head of the MOUAU Statistics Laboratory where he helps postgraduate
students to program and implement new findings and also teaches advanced procedures using the R
programming software and other related softwares like Python, SAS, STATISTICA, SQL, Excel,
etc. He is currently the postgraduate coordinator in the Department of Statistics, MOUAU and has
supervised several undergraduate students and a Masters student in Applied Statistics, Machine
learning and Data Science areas. Apart from making good contributions in paper
presentations/publications, Dr. John has also provided many statistical consultations and trainings
to many institutions and multinationals like the National Insurance Corporation of Nigeria
(NICON), Grambling State University, LA, USA, Selected Postgraduate Statistics Group from
Nnamdi Azikiwe University, Awka, UNFPA/Bureau of Statistics in Abia State, Nigerian Statistical
Association (NSA), Laboratory for Interdisciplinary Statistical Analysis (LISA), and the British
American Tobacco (BAT), but to mention a few.

RESERCH INTEREST

Applied Industrial Statistics and Data Analytics, Deep Learning, Multidimensional Scaling, and the
use of R and Python for statistical programming.
