Dr Sampson Twumasi – Ankrah is a Senior Lecturer in Statistics at the Department of Statistics and Actuarial Science, KNUST. He has extensive experience in vaccine research and surveillance studies.

Throughout my career, I have been deeply involved in various research projects that have allowed me to explore the intersection of statistics and biomedicine. My expertise lies in vaccine research and surveillance studies, where I have actively contributed to the development and evaluation of vaccines, including Typhoid Conjugate Vaccine Trial, Pediatrics iNTS Vaccine Trial, and the COVID-19 Herbal clinical trial. These experiences have not only enhanced my understanding of the statistical methodologies specific to vaccine trials but also allowed me to appreciate the critical role statistics play in improving public health outcomes.

In addition to my work in vaccine research, I have also ventured into the field of surveillance studies, focusing on environmental surveillance for diseases such as typhoid, and improving child health outcomes using mobile health information systems. By analyzing data on disease prevalence in the environment and implementing effective statistical methodologies, I have contributed to the development of strategies to mitigate the burden of these diseases. This work not only highlights my ability to adapt statistical techniques to different research domains but also showcases my dedication to addressing real-world public health challenges. I have extensive experience in electronic data capture platforms like REDCap, Commcare, and others.

Teaching has always been an integral part of my journey, as I strongly believe in sharing knowledge and inspiring the next generation of statisticians. With my expertise in statistics, econometrics, and biostatistics, I have successfully taught these courses at both undergraduate and postgraduate levels. I am known for creating an engaging and supportive learning environment that encourages students to excel. Moreover, I have had the privilege of supervising numerous students at various academic levels, providing them with guidance and mentorship to help shape their research careers.

What sets me apart as a statistician is my commitment to bridging the gap between theory and application. I am constantly exploring innovative statistical modeling techniques to address complex research questions. My research interests include time series analysis, econometrics, extreme statistics, and regression methods. By staying up to date with the latest developments in statistical theory and methodology, I aspire to tackle challenges in fields beyond biostatistics and facilitate evidence-based decision-making in various sectors.

As I progress in my career, my ultimate goal remains focused on making a tangible impact on research and practical applications. By combining my diverse expertise in biostatistics, econometrics, and vaccine research with my passion for teaching, I aim to contribute to advancements in statistical methodologies and their application to improve public health outcomes and inform evidence-based decision-making.

In summary, my experience in diverse applications of statistics, particularly in the fields of biostatistics and econometrics, along with my extensive knowledge in vaccine research and surveillance studies, positions me as a well-rounded statistician ready to make a meaningful contribution to the field. With my dedication to teaching and mentorship, I want to inspire future statisticians to embrace the power of statistics in addressing critical challenges and shaping a healthier and more informed society.
