About Me


Dr. AnneMarie W. Block joined the staff of Roswell Park Comprehensive Cancer Center (Roswell Park) in 1985 as a Cancer Research Scientist and Clinical Cytogenetics Laboratory Supervisor. She was appointed Director, Clinical Cytogenetics Laboratory, Department of Pathology and Laboratory Medicine in 1988.

Dr. Block earned her doctoral degree in Physiology at UB in 1986. She is a Founding Fellow of the American College of Medical Genetics, a diplomate of the American Board of Medical Genetics (Clinical Cytogenetics, 1990), and has a New York State Certificate of Qualification as a Clinical Cytogenetics Laboratory Director.

Dr. Block is actively involved in graduate medical education and is the course coordinator for “Oncology for Scientists” (RPN 530-532) a year-long comprehensive survey course offered through the Roswell Park Graduate Division.

Dr. Block is a member of Cancer and Leukemia Group B, Children’s Oncology Group, American Society of Human Genetics, American Society of Hematology, American Society of Clinical Oncology, American Association for Cancer Research, American Association for the Advancement of Science, Association of Genetic Technologists, Association of Women in Science, American Association of University Women, Sigma Xi, American Society of Clinical Pathologists, American Association for Cancer Education, Inc., and the New York Academy of Sciences.

Research Overview:

Dr. Block’s research interests focus on chromosome abnormalities in B-cell lymphoproliferative disorders with an emphasis on tracking patient progress, survival, response to treatment and aid in therapeutic decision-making; mitogenic stimulation of human B cells; sister chromatid exchange analysis; chromosome aberration analysis; and fluorescence in situ hybridization (FISH) analysis of solid tumors and hematologic malignancies.
