Research Grants


My research is currently funded by NIH grants.

My research covers two broad areas: methods for mapping genes for complex diseases and methods for analysis of genomic data. From 1998 to 2012, I was supported by an NIH R01 grant (ES009911) to develoop methods for mapping genes for complex diseases, including methods for linkage, association, haplotype and admixture mapping. My method research on genomic data analysis is supported by a NIH R01 grant, focusing on developing statistical and computational methods for analysis of genomic data with graphical structure, and another R01 grant focusing on analysis of next generation sequencing data. I am also the PI of a T-32 traininng grant "Training in Ophthalmic Statistical Genetics and Bioinformatics" to train investigators in the area of statistical genetics for ophthalmic genetics.

I also collaborate with other people on genetic studies of complex diseases and biological systems. I worked with Dr. Glenys Thomson on the Biostatistics Core for the 13th International Histocompatibity Working Group and was the PI of Biostatistics and Bioinformatics Core for the Project "A Mitochondrial Longevity Pathway: P66Shc Mechanisms" during 2007-2008. Funded by several NIH R01 grants, I am also collaborating with Dr. Maris, Dr. Struan and Dr. Hakonnarson at the Children's Hospital of Philadelphia on genome-wide association studies of neuroblastoma, childhood obesity and childhood asthma. Finally, I am collaborating on several projects on analysis of human gut and lung microbiome studies (collaborators: Ron Collman, Rick Bushman, Gary Wu and Jim Lewis).
