Research Summary

I have been heavily involved in the field of salivary gland cancer research since my postdoctoral experience during residency in the lab of Drs. David Sidransky and Joseph Califano. I joined the Johns Hopkins Department of Otolaryngology as a faculty member in 2006 and chose to focus my research efforts on salivary gland tumors, with several NIH and foundation grants awarded since 2007. My focus was on the epigenetic mechanisms of adenoid cystic carcinoma, and the pathways that might lead to its development. Since moving to UCSF in 2015, our lab has pivoted to studying the function of the Myb-NFIB fusion oncogene present in adenoid cystic carcinoma in an effort to better understand the molecular underpinnings of this elusive cancer. We continue to work with many collaborators at UCSF and throughout the world. As a practicing head and neck surgeon, I bring additional clinical expertise which can offer access to tissue banking and patients, as well as an understanding of the relevant translational questions.
