In 1995 when I was a junior faculty at Cornell Medical Center in New York City, a Cytopathology fellow and I modified Papanicolaou stain for fine needle aspiration (FNA) cytology to hemolyse aspirated blood and shortened the time from 20 min to 90 sec by adding formalin. I was then invited by a radiology office one day a week to provide on-site assessment for their patients underwent ultrasound and CT-guided FNA biopsies. See link:

Subsequently, I was recruited to New York University Medical Center (1996-2006). In 11/2006, I returned to Cornell, where I correlated my FNA diagnoses to the histopathology of the thyroidectomies of the private radiology patients. The data collected have been summarized in this thyroid book. Link to citation index of my publications:
