Dr. Josephine Asafu-Adjei is a research assistant professor with more than seven years of experience as a statistical researcher, who specializes in developing and implementing statistical methods in studies geared towards nursing, public health and neuroscience research.

Dr. Asafu-Adjei focuses her expertise on developing variable selection methods that will improve selection accuracy in studies utilizing matched case-control designs.

As a Research Fellow at the Harvard T.H. Chan School of Public Health, Dr. Asafu-Adjei was responsible for both creating and implementing variable selection techniques with direct applications to studies in neurodegenerative and cardiovascular disease research. She also developed a pseudo-likelihood approach to Bayesian classification methods with applications to high dimensional data sets.
