My research interests are primarily focused on understanding the development and pathobiology underlying rare melanomas (such as mucosal, acral, and ocular melanomas) in order to 1) identify risk factors to improve prevention and early detection, 2) develop novel tumor/blood diagnostics for rare melanoma subtypes, 3) establish methods for halting progression and eliminating micro-metastatic disease, and 4) improve efficacy of current therapies (targeted and immunotherapies) and develop new treatment modalities which are effective for rare melanoma patients
