Professional Interests:

The focus of our research is the molecular pathogenesis of papillary thyroid cancer (PTC). We are using RNASeq to interrogate the landscape of gene expression alteration in PTC in clinical samples. By comparing PTC and samples of normal tissues from the same patients we have gained insight into the molecular changes driving PTC, as well as potential therapeutic targets. As men have a lower incidence of PTC than women, we are concentrating on the role of androgens in the etiology and progression of PTC. Our results indicate that androgens exert an anti-proliferative effect and result in a G1-S block in the cancer cell cycle.
