Harvard Catalyst Profiles

As a biostatistician working at the Division of Preventive Medicine at Brigham and Women’s Hospital, my research interests are three-fold:
1) conducting biomarker discovery studies using high throughput metabolomics and other -omics data;
2) analysis of Electronic Health Records data;
3) methodological statistical research on building valid risk prediction models.
My clinical research focuses on the mechanistic pathways of cardiovascular disease development and progression.

The following publications highlight some of my research activities:
