Research Interests

Within the framework of a variety of collaborative and methodological projects, my overall research goals are to ensure that scientific research is carried out that utilizes appropriate statistical methodology. Sometimes this is achieved through application of existing statistical methods and in other instances it involves development of new methodology. My research encompasses several collaborative and methodological subject areas: clinical research related to stem cell transplantation, reproductive epidemiology and developing new statistical methods for the analysis of medical diagnostic test data.

A major focus of my research is collaborative work with clinical investigators who are based in the Center's Clinical Research Division (CRD). CRD is world renown for its pioneering work in stem cell transplantation where the procedure was first used approximately 30 years ago. In collaboration with principal investigators from several large program project grants in the CRD, I carry out the design and analysis of Phase I, II and III clinical trials which aim to further expand and improve our ability to treat patients with a wide range of diseases and prognoses. Over the long history of transplantation at the Center, our group has also developed a large database of patient data that allows us to carry out retrospective analyses to generate hypotheses for future prospective studies.

For patients undergoing stem cell transplantation, infection is a very serious development and more accurate and earlierdetection of disease is an important research topic amongst infectious disease researchers. More globally, diagnostic and screening programs are becoming a large and costly component of our health care system. It is therefore important that research leading to the implementation of new tests be rigorous in determining the accuracy of the tests. A primary goal of my methodological research is to develop statistical methods that allow researchers to answer relevant clinical questions about diagnostic tests. We have described marginal regression methods for the comparison of multiple diagnostic tests and evaluation of covariate impacts on sensitivity and specificity parameters when one or more test outcomes are obtained on each subject studied. Additionally, we developed a new regression methodology for diagnostic likelihood ratios, quantities that describe the degree to which the outcome of a diagnostic test revises the pre-test odds of disease. Most recently, we have developed a statistical test for the comparison of predictive values of diagnostic tests when the data was obtained under paired study designs.
