I am a physician-scientist trained in Anatomic Pathology, dermatopathology, and molecular genetic pathology. My doctoral research focused on improving our understanding of the features, drivers, and heterogeneity of melanoma brain metastases to improve our ability to treat this deadly disease complication. My current research utilizes a combination of bionformatics and wet lab techniques to improve our understanding of the molecular pathology of melanoma and other cutaneous neoplasms.
