We are interested in the genetic basis of complex human disease, using genetic/genomic approaches coupled with statistical genetic, genetic epidemiologic and bioinformatics methods to more fully discover causal genes that can be functionally characterized. Our research uses genome-wide approaches to identify loci in the human genome that then require more detailed interrogation to establish putative candidate genes, and the variants in the genes that contribute to disease risk. Our primary diseases of interest are type 1 diabetes, diabetic nephropathy (kidney disease), autoimmunity, atherosclerosis, cardiovascular and cerebrovascular diseases.

The genomic technologies (both laboratory and analytic) have rapidly evolved over the past decade. Our studies have included family-based, case-control and cohort collections. Our approaches have included genome-wide linkage, association, fine-mapping, targeted sequencing and exome sequencing. Functional approaches have now expanded to RNAseq and characterization of specific genes by using targeted assays and model systems. Collaborations are typical of our work, including the NIDDK/JDRF Type 1 Diabetes Genetics Consortium (T1DGC), the NHLBI Exome Sequencing Project (ESP), and the NHLBI Multi-Ethnic Study of Atherosclerosis (MESA). Our current work addresses the need to better understand the complex genetic architecture of common human disease from genomic diversity and how this diversity interacts with environmental risk factors to define a risk profile for a variety of disorders.
