Personal Statement

By way of training, I am a board certified anatomic and clinical pathologist with subspecialty boards in cytopathology and a subspecialty fellowship in gynecologic pathology. I have a broad expertise in most areas of surgical pathology having practiced as a general surgical pathologist for over 20 years. I have a special interest in the pathology of the female reproductive tract, particularly cervical pathology, having trained at the Brigham and Women’s Hospital in Boston. For the past seventeen years, I have been Director of Anatomic Pathology at the University of New Mexico Health Sciences Center overseeing all aspects of surgical pathology and cytopathology. My work at the University of New Mexico has been a combination of clinical service through diagnostic general surgical pathology and cytopathology, education of medical students, pathology residents and fellows, and research with a focus largely in gynecologic malignancies. I have a long-time interest in global health and have worked providing pathology services and education to underserved populations in Central and South America, Africa, and Central Asia.
