Position (back to top)

Research fellow

Lab Role (back to top)

Responsible for statistical analysis of biological data, including genome-wide association studies (GWAS) of various phenotypes that aim to discover genetic variants and their interactions with environmental factors.

Expertise (back to top)

Statistics, statistical genetics/genomics and statistical computing.

Research Interests (back to top)

Identifying genetic variant underlying complex traits and their interaction with environmental factors is challenging. It requires specialized statistical methodology and computational tools. My research is to develop state-of-the-art methods and efficient algorithms for analysis of complex traits. In addition to analyzing multiple traits separately, I also study how to best analyze them jointly and produce results that facilitate biological interpretation.
