Xu, Tina

Research Interests:

Tina has developed a series of statistical methods in modelling the infection rate and fatality rate for an emerging epidemic. Her current research interest focuses on statistical modelling with applications to clinical trials, especially the vaccine studies. She also has experience in designing, conducting and analyzing clinical trials and has been engaged in various clinical projects in the areas of influenza prevention, glaucoma, dental cancer and neonatal infection.
