Jiwei Zhao
PhD
Research Topics
Statistical methodology including semiparametric modeling and methods; non-regular likelihood methods (including pseudo, penalized, conditional, empirical, etc.); missing data analysis (especially non-ignorable missing data) in longitudinal data and observational studies; case-control studies; high-dimensional data analysis and variable selection. Zhao also has research interests in a number of subject-matter applications and collaborations, including: epidemiology; cancer; women's health; environmental health; mental illness; and substance abuse.
