Personal profile

Research Interests

I am a board certified pathologist with subspeciality certification in cytopathology. My primary intereststs are gynecologic cytology (cervical cancer screening), fine needle aspiration of head & neck/thyroid, and general cytopathology. I am widely published (over 160 books and journal articles) in these areas and one of my major contributions has been the co-editorship of the Bethesda system for used for reporting Pap smears in women all around the world. Advocacy for my chosen discipline of pathology and women in medicine as well as medical education are my other interests. I serve as the Vice Chair for Education and Faculty Development for the Department of Pathology at Northwestern FSM. I am also very active in volunteering my effort and expertise in organized medicine and have major leadership roles in a number of national and international pathology organizations. In 2013 I served as the President of the American Society of Cytopathology (http://www.cytopathology.org) and am a current member of the Executive Council of the International Academy of Cytology (http://www.cytology-iac.org/. In 2016, I was elected to serve as a Trustee of the American Board of Pathology. I am a frquently invited speaker/teacher for cytopathology at both national and international scientific meetings.

My clinical work involves diagnosis of cytopathology specimens obtained by fine needle aspiration biopsy, exfoliative cytology and core biopsy techniques in the pathology department at Northwestern Memorial Hospital.

My educational activities including teaching medical students, residents and fellows in cytopathology at Northwestern and I am also an invited speaker, panelist and moderator at numerous national and international pathology professional society scientific meetings. I focus my translational research endeavors in cytopathology with particular emphasis on thyroid and gynecologic pathology. I am the co-editor of the Bethesda system for reporting Cervical Cytology- this is the terminology used to report Pap smears all around the world. The Bethesda System became the prototype for subsequent terminology systems such as thyroid, urine, pancreaticobiliary, and salivary gland.
