Aihua Liu, Ph.D.

Right after finishing my Ph.D study, I joined the Verglas Project as a statistician. Mainly my work is to manage data, analyze data, interpret results, and involve in writing manuscripts. Be doing this, I work with my supervisors and colleagues in the project together to investigate the influence of prenatal stress on the physical growth, functioning, cognitive development, and behavior of the children exposed to such stress.

My first post-secondary education was completed at Beijing Medical University in China, where I received a bachelor degree of medicine with a focus on preventive medicine. Motivated by the desire to improve myself and my career, I came to McGill University to start my Master study in the Department of Epidemiology and Biostatistics, and then a Ph.D study in the same department. During my Ph.D study, I had been focusing on the methodological issues of testing and estimating interactions.
