BIOGRAPHY OF DR. OYAMAKIN

My name is Oyamakin Oluwafemi, I hold a BSc, MSc and PhD degrees in Statistics from the University of Ibadan. I am also a Fellow, Graduate Statistician, Chartered Statistician and Chartered Scientist of the Royal Statistical Society, United Kingdom. My professional associations include; Nigeria Statistical Association, Nigeria Statistical Society, International Biometric Society, Nigeria Mathematical Society, International Statistical Institute (ISI) among others. I am currently the Master's degree coordinator and a lecturer in the Department of Statistics, University of Ibadan with passion for teaching and conducting research in statistics utilization, modeling and practice. I have collaborated with researcher from other disciplines like medicine, forestry, Sociology among others within and outside the country. In 2012, being the consultant to CENRAD on statistics, I was one of the delegates invited by UNDP (REDD+) to advance knowledge in Climate change modeling. I was also a participant in the WHO/TDR Programme on Implementation Science. Oluwafemi is a Mentee under the aegis of the Havard T. H. Chan School of Public health and the Africa Research, Implementation Science and Education (ARISE)

Network and one of the two ISI Ambassador selected to attend International Biometric Conference in Barcelona, Spain. Among my numerous skills are, Teaching of statistics courses at undergraduate and postgraduate levels (especially Theories of Demography, Probability, Biometry & Applied Statistics), Research/proposals writing in Forestry, Agriculture and Public Health studies, Designing, Collecting, Organizing, Conducting and Analyzing demographic survey/field data, Writing and presenting research reports. I am proficient in Microsoft Office (Word, Excel, etc.), E-views, SPSS, MINITAB, STATA, R, MATLAB and PYTHON. I have facilitated at several training programmes like UI-LISA Training/Workshop on Logistics Regression using R, Statistical Workshop and Training on the Use of SPSS and R. Monitoring and Evaluation Workshop by University of Ibadan Research Foundation (UI-RF) among others. I have expertise in Designing research instruments for field and experimental researches, model development, tests and validation with good exposure in and out of Nigeria in offering a first-class service that put our clients in the fore front of their competitors.

Alternative Nonlinear Growth Models for Biological Processes

The work modified the source differential forms of the Malthusian perspective and its variants and came up with five new growth models as alternative to the existing Exponential, Monomolecular, Gompertz, Richards and Von Bertalanffy growth models using Hyperbolic sine function. The developed models provided boundedness for the exponetial growth model and improved the growth processes in the other models through the allometry parameter that controls the shape of the growth curve. Data from different sources were used to validate the effectiveness of the developed model so as to determine its suitability and validity. Furthermore, the developed models along with the existing ones were subjected to violation of assumptions so as to test how robust they are to outliers or shocks. At various degree of contamination of outliers ranging from 50%, 100% and 500% of the highest and lowest values were considered and the developed models demonstrated a better ability to accommodate shocks over the existing ones. Hence, I recommend usage of our developed models when study that requires the use of growth models is being carried out.
