My lab studies how genetic variation predisposes individuals to develop cardiovascular (e.g. myocardial infarction) and hematological (e.g. sickle cell disease) diseases, or how the same genetic variation modulates disease severity. We use modern genetic and genomic approaches, such as genome-wide association studies and next-generation DNA re-sequencing, to identify genetic risk factors for these diseases. Projects in the lab could involve: (1) analyzing complex genetic datasets, (2) developing new algorithm for data mining and integration, and (3) molecular and cellular functional validation of new genetic discoveries.
