Dr. Bakoyannis' methodological research is focused on the nonparametric and semiparametric analysis of survival and competing risks data as well as Markov processes, with a special emphasis on issues commonly arising in biomedical and clinical research, such as missing data, outcome misclassification and interval censoring. The motivation for his past and current methodological research came from various collaborative research projects in which he participated as a biostatistician, mainly in the field of HIV/AIDS epidemiology. Dr. Bakoyannis has served as a technical advisor for the Reference Group on Estimates, Modelling and Projections of the Joint United Nations Programme on HIV/AIDS (UNAIDS) on issues related to estimation of mortality under misclassification due to death under-reporting.

 

Additionally, Dr. Bakoyannis is interested in collaborative research in a majority of biomedical and clinical fields including but not limited to HIV/AIDS, cancer and other chronic diseases, Occupational and Environmental Epidemiology and health-related behavioral issues.
