About Me

I am the director of the Division of Endocrinology, Diabetes and Metabolism at The Ohio State University. I also serve as co-leader of the Cancer Biology Program at the OSUCCC – James and hold the Ralph W. Kurtz Chair in Hormonology.

As a specialist in thyroid cancer, my research is focused on molecular mechanisms involved in thyroid cancer invasion and metastasis, with an active interest in new drug testing for thyroid cancer therapy.

Among my current research activities is serving as principal investigator (PI) for a National Cancer Institute (NCI) grant-funded study of the role of p21-activated kinases in thyroid cancer. My colleagues and I have identified a potentially important pathway (p21 activated kinase, or PAK) downstream of the BRAF gene that may be involved in the progression of papillary thyroid cancer, which is incurable when metastatic and progressive. My team hopes to determine the relevance of the PAK pathway in vivo, clarify the mechanism by which it is activated and test novel compounds that block PAK activation with the goal of determining whether PAK is a viable therapeutic target.

I also served as PI for a multimillion-dollar, NCI-funded program project grant (PPG) to study genetic and signaling pathways in epithelial thyroid cancer, as well as an NCI-funded Specialized Program of Research Excellence (SPORE) grant to help improve the lives of patients with thyroid cancer. Both grants entailed several interactive projects and multiple investigators at Ohio State and other academic institutions.

In addition, I have authored or co-authored numerous scientific articles in such prestigious journals as Nature Communications, Journal of the American Medical Association, Annals of Surgical Oncology and Human Molecular Genetics.
