Director, Cytogenetics Laboratory

Associate Professor of Pathology

Research Interests: Cytogenetic diagnosis; Translational research; Detection and characterization of subtle chromosome abnormalities in hematological malignancies


Dr. Yi Ning is an associate professor of pathology at the Johns Hopkins University School of Medicine, and the director of cytogenetics laboratory in molecular pathology division. She co-directs Oncology Tissue Services at the Johns Hopkins Kimmel Cancer Center.

Her research focuses on the detection and characterization of subtle chromosome abnormalities in hematological malignancies. In addition, she has contributed to the development of human chromosome-specific telomere probes and the application of spectral karyotyping for the improvement of cytogenetic diagnosis.

Dr. Ning received clinical and research training at Baylor College of Medicine and the National Human Genome Research Institute, NIH. She is a clinical cytogeneticist certified by the American Board of Medical Genetics. more
