Staff Profile
Dr Chibuzor Nnanatu is a talented Lecturer with the Department of Statistics, Nnamdi Azikiwe University Awka. My areas of expertise span over Bayesian statistics, Computational statistics, and Spatial & Spatio-temporal statistical modelling with focus on tackling topical environmental and public health issues including environmental pollution, and promotion of child and maternal health. I have a BSc (Unizik), MSc (Unizik) and PhD (Lancaster) all in statistics with teaching and research experience spanning over 12 years. My current research activities evolve around the development of novel Markov chain Monte Carlo (MCMC) algorithms and integrated nested Laplace approximation (INLA) techniques for the analysis of complex household surveys data such as the Demographic and Health Survey (DHS) and Multiple Indicator Cluster Survey (MICS), and data emanating from partially observed complicated endemic diseases including Covid-19.
