Research Interests
Yonas' primary research interests are in the statistical design and analysis of observational studies. In particular he has been working in extending the methodology and application of the self-case series method. He published several papers and a book on the self-controlled case series method. He has also developed an R software package (SCCS) for the method. His other interests include Clinical trials, longitudinal data analysis and missing data analysis. Currently, he is working in developing a statistical model for early detection and predication of gestational diabetes and associated maternal and fetal complications. He also consults on bids for funding via Research Design Service (RDS).
