We study relationships between genetic variation and phenotypic traits using statistical methodology. A broad class of such problems is related to association mapping of genetic polymorphisms that are involved in disease susceptibility, response to medicine, and differential reactions to environmental exposures. Development of novel statistical methods to accompany technological advances is essential in order to further efforts to improve health-related quality of life and treat and prevent disease. Identification of genetic pathways whose dysfunction leads to disease can help to accelerate understanding of environmentally induced disruptions of those same pathways. Human genetic data is currently being produced at an increasing rate. The sheer volume of data and its complexity create new challenges for methodological research. How not to drown in the data while extracting useful signals? Our research focuses on developing efficient methods for detecting and characterizing genetic associations with discrete and quantitative traits, while taking into account the large and expanding scale of genomic data.
