Research Interests
|
The focus of my research is developing statistical methodologies for genetic mapping of complex traits. In particular,
I have developed
trait-model-free approaches for linkage detection using extended
pedigrees. My general interest includes computational statistics, parametric and nonparametric inferences and their application in different areas of
statistical genetics.Currently I am working on modeling heritability, association between multiple variants (both rare and common) and single or multiple traits
in case-control/cohort or in family studies . My methodological research is supported by NIH/NIDA R01 and NIH/NIDDK R21. I am also involved as a co-investigator in several R01s led by faculty in Epidemiology and Psychology. My
collaborative work involves addressing statistical issues in pedigree-based or cohort-based genome-wide association studies. I have developed and applied my methods to a variety of diseases, including type 2 diabetes, Alzheimers, kidney allograft rejection, substance abuse, venous thrombosis, and graft-versus-host disease post hematopoetic stem cell transplant.
I am currently the co-director of a statistical genomics training grant. More information about the training program can be found here
