Research Synopsis

My research focuses on several aspects of nutrition (in particular, folate and folic acid ) and cancer (in particular, colon and breast cancers) at the molecular, cellular and translational levels, including prevention, early detection and screening, development and validation of surrogate endpoint biomarkers, molecular genetics and epigenetics, and pharmacogenetics using animal models, cell culture systems and human subjects. More recently, my research program has expanded to investigate the effects of maternal and early life nutrition on epigenetic programming and cancer risk of the offspring.
