Personal Statement
Prof. Duah Dwomoh (CEO and Founder of D&D) is an Applied Statistician with a special focus and interest in statistical methods applied in the fields of Public Health, Implementation Science, Monitoring and Evaluation, Education, Epidemiology and Disease Control, Predictive Modelling, Social and Behavioural Sciences, Pharmaceutical Analytics and Banking and Finance and Infectious Diseases Modelling. He has more than 15 years of practical experience in teaching at the University and conducting research in the aforementioned areas. He has more than 65 publications in peer-reviewed journals. Prof. Dwomoh obtained a Ph.D. in Public Health with a specialization in Biostatistics from the University of Ghana, a Master of Philosophy in Mathematics with a specialization in Statistics from Kwame Nkrumah University of Science and Technology, and a BSc in Mathematics and Statistics (First Class Honours) from the University of Cape Coast, Ghana. He is currently an Associate Professor at the University of Ghana, School of Public Health, Department of Biostatistics, and the CEO of D&D Statistical Consulting Services Limited. He has expertise in both quantitative research methods and qualitative techniques. He has expertise in using different statistical methods for impact evaluation of health, Agriculture, Education, Pharmaceutical and social interventions/programs/policies including but not limited to differences in differences analytic methods, matching procedures, regression discontinuity, instrumental variables, randomized designs, endogenous regime-switching regression models, interrupted time series, endogenous treatment regression models, double robust methods, treatment effect estimate using Least Absolute Shrinkage and Selection Operator, and synthetic control methods. He develops the framework for project monitoring and evaluation for formative/process evaluation, situational analysis, needs assessment, mid-term project review, outcome and impact evaluations, and develops a project performance monitoring plan with relevant data collection systems including review and assessment of the quality of existing data in the project areas, the data collection techniques, and determining a good baseline statistics for subsequent impact evaluation of the outcome measures. He is a proficient programmer in Stata, SPSS Epi-Info, Epicollect, R, and ATLAS.ti, Dedoose and Nvivo, Open Data Kit, CSPro, KoboCollect, Survey Monkey, REDCap, Google Forms, and Microsoft Forms. He has tremendous data management skills including exporting and merging large complex survey datasets from multiple sources, and the ability to implement quality assurance protocols. His area of specialization as an Applied Statistician includes the design, implementation, and analysis of complex survey data that adjust for survey design characteristics (weighting, clustering, and stratification), design and implementation of randomized control trials, quasi-experimental and observational (cross-sectional) studies, data science, risk prediction modelling, time series analysis, Generalized Linear Models, and analysis of survival or time-to-event outcomes. In the context of merging, cleaning, coding, and analyzing complex survey data, Stata MP (StataCorp, College Station, Texas, USA) is my preferred statistical software. In-depth knowledge in machine learning applications such as logistic regression with Least absolute shrinkage and selection operator, Ridge regression, Random forest, Elastic Net, k-nearest Neighbour, Random Forest, Support Vector Machine, Gradient Boosting Machine, Extreme Gradient Boosting (XGBoost), Bayesian Generalized Linear Model, and Light Gradient Boosting algorithms, Linear Support Vector Machines (without kernel extensions), Naïve Bayes, and multi-layer feedforward artificial neural networks, Support Vector Machines using Polynomial Basis Kernel. He has expertise in the mathematical modeling of infectious diseases using stochastic and deterministic models based on systems of differential equations. Prof. Dwomoh has supervised post-graduate thesis on the design and use of complex surveys, Impact and Process Evaluation of Health Interventions, Public Health, Health Informatics, and Biostatistics.
