Summary of research:
As a biotatistician, Dr. Rosychuk develops new statistical tools to solve complicated problems and contributes her statistical expertise to medical studies. Statistical research can be classified as an essential science that includes the development and investigation of new mathematical techniques to solve problems in areas of application such as medicine and health. Developing new and better statistical techniques contributes to the analysis and interpretation of medical studies that lead to advances in knowledge. Dr. Rosychuk focuses her statistical research program on methods for improved design and analysis of medical studies. Specifically, the primary interests involve geographic surveillance and medical diagnostic studies. The geographic surveillance work involves disease cluster detection methods that seek to identify geographic areas with higher disease rates than would be expected by chance. Her diagnostic medicine work includes methods for potentially misclassified data, such as results from an imperfect diagnostic test. Ideally, these statistical methods are motivated by real data obtained from collaborations with medical researchers.
