Klaus Schreiber, M.D., is a board-certified anatomic pathologist, specializing in Cytopathology. He was graduated from University of Vienna, Medical School and completed his pathology residency at the Francis Delafield Hospital of Columbia University. He then had a fellowship in cytopathology at Memorial Sloan Kettering Cancer Center in NYC under the direction of Dr. L.G. Koss, one of the founding fathers of cytology.
Klaus and Dr. Koss became colleagues authoring numerous studies on the cytologic precursors to cancer.
In 1984, his studies of cytological material derived from endometrial abrasions in 4,000 asymptomatic women established the first known incidence statistics for occult endometrial carcinoma and precursors. Several years later the findings of this study (1.7/1000 years) were confirmed by the Women's Health Study which consists of long-term surveillance of 175,000 US women.
Dr. Schreiber was the director of cytopathology at Montefiore Medical Center, including the Albert I. Einstein College Hospital, for 20 years.
In 1990, he along with Dr. Koss and others collected cytological images from smears to teach and construct a neural net. In early 1990s, Dr. Schreiber became a consultant to PapNet (an AI based scanning system for gynecologic smears), and then helped teach/build the CDx Diagnostics/WATS3D neural net.
Teaching is a passion of Dr. Schreiber; and after a long illustrious career teaching cytopathology at Albert Einstein College of Medicine, he was awarded the title of Emeritus Professor of Pathology at Albert Einstein College of Medicine. Dr Schreiber believes teaching to be his signature achievement.
