Area(s) of Specialization:
Metabolomic studies, pediatric HIV studies, measurement error in self-reported outcomes, study design, high dimensional data and analysis of biological networks.
My research is motivated by studies of complex disorders in large epidemiological studies such as the Women’s Health Initiative. My interests are in methods for biomarker discovery in metabolomics studies, biological network analysis and measurement error models.
