Research and Clinical Interest Summary:

As a resident in Anatomic Pathology, my subspecialty interests were Cytogenetics/Molecular Pathology and Dermatopathology.  As a passionate researcher, I seized the opportunity to merge these interests with an in parallel Post-Doctoral Residency Fellowship studying the genetics of nevi and melanoma, for which I was awarded the House Staff Award Clinical Research Grant in 2003.  During my research fellowship, I also participated in clinical evaluation and germline mutation analysis of patients with genodermatoses, such as Brooke-Spiegler syndrome, multiple familial trichoepithioma, familial cylindromatosis, Hermansky-Pudlak syndrome, familial atypical multiple mole melanoma syndrome, and dysplastic nevus syndrome; experience which later became an asset both while assisting in the dermatology clinics during my Dermatopathology Fellowship and as a practicing Dermatopathologist, who serves high risk practices.  

My research focus transitioned to non-invasive diagnostics and diagnostic imaging of the skin during my Dermatopathology Fellowship after being recruited into the field of Reflectance Confocal Microscopy by the world’s leading expert, Dr. Salvador Gonzalez.  Soon thereafter, Dr. Gonzalez and Dr. Allan Halpern (both of Memorial Sloan-Kettering Cancer Center) invited me to co-edit the first textbook on Reflectance Confocal Microscopy.  As one of the few Dermatopathology-trained experts in this emerging subspecialty (diagnostic imaging of the skin), my research goal is to collaboratively pioneer more efficient, higher quality, safer care via non-invasive optical imaging, sparing patients unnecessary invasive biopsies and, for lesions that require removal, enabling same day diagnosis and definitive therapy, minimizing direct and indirect (time) cost to both healthcare system and patient.
