Research Focus

Dr. Lim's research focuses on the role lifestyle factors play in the development and the racial and ethnic disparities of common sporadic cancers and dementia.  She is particularly interested in using different types of biomarkers (blood biochemistry, DNA methylation, the gut microbiome, imaging) in tandem with questionnaires to assess exposures and risks.

Some of her recent research questions included the following:

  1. How the risk of Alzheimer’s and related dementia varies across racial and ethnic populations and how the disparity is explained by the distribution of known genetic and non-genetic risk factors?
  2. How genome-wide methylation patterns in pre-disease blood DNA are associated with disease occurrence and can serve as risk predictors?
  3. How well the prediction scores for visceral fat and liver fat perform to explain associated metabolic disease risks?
