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.
