BIO STATEMENT

I am a statistician and PhD candidate in Public Health at KNUST with extensive experience in data management, statistical analysis, and clinical trials. My work spans disease surveillance and modeling, vaccine trials, spatial analysis, and e-health. I focus on infectious disease modeling to understand transmission dynamics, identify key drivers, and optimize resource allocation. I have collaborated with organizations like the International Vaccine Institute, Americares Foundation, and UNDP, and served as statistical consultant for health interventions. Recently, I participated in a summer-visiting-fellows program at the University of Pennsylvania and completed the Penn Implementation Science Institute. I have also led workshops on data analysis, statistical tools and research methodology.

Recent Global Health Projects

1) Modeling of infectious disease, the case of typhoid fever in Ashanti Region og Ghana. this study seeks to understand transmission dynamics, identify drivers of disease spread, and optimise resource allocation for effective disease control in Ashanti Akim North District of Ghana.

2) Burden of febrile illness complications and determinants of typhoid fever complications in the Ashanti region of Ghana: This study aimed to assess the prevalence, types, and risk factors of complications in febrile patients, with a specific focus on typhoid fever in the Ashanti region of Ghana. The study highlights a significant burden of complications among febrile patients in Ghana, with typhoid fever as a major concern. Delayed healthcare-seeking behaviour significantly increased the risk of typhoid complications, while the rural residence appeared to be protective. These findings underscore the need for timely diagnosis, prompt treatment, and health education, especially in urban areas. Strengthening preventive strategies, including vaccination, remains essential to reducing typhoid-related complications and mortality
