Research Interest

According to the California Cancer Registry, thyroid cancer incidence is higher in young Filipino Americans than Caucasians or any other Asian women.  This report highlights how the distribution of risk factors among Californians can impact the cancer burden in this state.  Overall, out of 35% of Californians with thyroid cancer show 6% points higher than the national average.  Very few risk factors are known that predispose to the development of thyroid cancer.  Thyroid carcinogenesis is a multistep process involving a multifactorial interplay between genetic and environmental factors. As a Cancer Biologist, intensive training in Clinical Oncology, Molecular Genetics and Pathology, my research interest is to elucidate how Genetic and environmental factor interplay in thyroid cancer health and gender disparities.  My focus is to elucidate the underlying mechanism of the disease and prevent the further progression from well-differentiated to poorly differentiated thyroid cancer. The research project is divided into two parts: Clinical problem analysis (translational): how a minimally invasive molecular biomarker can distinguish benign from malignant nodules; basic science: how differential molecular mechanism determines thyroid cancer health disparities.
