Xiao P. Peng

Xiao P. Peng, MD, PhD, is Director of the Genetics of Blood and Immunity Clinic and Co-Director of the New York Center for Rare Diseases at the Children’s Hospital at Montefiore Einstein and Assistant Professor of Pediatrics and Genetics at our Albert Einstein College of Medicine. Dr. Peng cares for patients with complex, undiagnosed disorders, with unique and specific expertise in the diagnosis and care of genetically-driven disorders of blood and immunity (GBIs). She integrates the tools of molecular medicine and the conceptual understanding of human genetics and pathobiological mechanisms to identify novel disease-causing mechanisms and strategies for helping patients.

After receiving her Bachelor of Science in chemistry from the California Institute of Technology in 2005, Dr. Peng earned her Doctor of Philosophy in biochemistry and cellular and molecular biology at Sloan Kettering Institute in 2015 and her Doctor of Medicine at Weill Cornell Medical College in 2017. She then completed a pediatrics-medical genetics combined residency at Johns Hopkins University in 2021 and served an additional year as both Chief Resident and a Research Fellow. During her residency and fellowship, she also worked as a geneticist for the Genetics and Genomics Unit at the Center for Chronic Immunodeficiency, University of Freiburg, Germany.

Dr. Peng’s research focuses on the nexus of genome maintenance, transcriptional gene regulation and post-translational modifications. She is greatly interested in host-pathogen co-evolution, or how interactions with our fellow species, particularly microbes, have shaped human genomes and human history. She has been principal investigator and co-investigator on a number of funded research projects and contributed her time to many initiatives that advance the goals of the GBI community at large. Her work has been published in numerous peer-reviewed journals, case reports, book chapters, monographs, reviews and abstracts, and she has given many invited presentations. She serves in several groups within the ClinGen Immunology CDWG and as a reviewer for Genetics in Medicine, Clinical Immunology, Frontiers in Immunology and the Journal of Clinical Immunology.

Dr. Peng is board certified by the American Board of Medical Genetics and Genomics in Clinical Genetics and Genomics and the American Board of Pediatrics in General Pediatrics. She holds multiple leadership roles in the North American Immuno-Hematology Clinical Education & Research (NICER) Consortium. She serves as Geneticist for the Johns Hopkins Ataxia Telangiectasia Clinic and the Genetic Disorders of Mucociliary Clearance Consortium and Related Research Network. She is also an active member of the Clinical Immunological Society (CIS) and the European Society of Human Genetics.
