About Us

Stem Cell Program Executive CommitteeDr. Laurie Jackson-Grusby, Dr. Jordan Kreidberg, Dr. Joyce Bischoff, Dr. Leonard Zon, Dr. Louis Kunkel, and Dr. Xi He.

The Stem Cell Program Executive Committee provides consultation on issues ranging from community education and outreach through review of policies and procedures for stem cell research. Each member brings significant experience and expertise to the mission of the Stem Cell Program at Boston Children’s Hospital.

Joyce Bischoff, PhD
Associate Professor, Department of Surgery
Joyce Bischoff received her PhD in biochemistry from Washington University School of Medicine and trained as a postdoctoral fellow in cell and molecular biology at the Whitehead Institute for Biomedical Research. She joined the Surgical Research Laboratory, now the Vascular Biology Program at Boston Children’s Hospital, in 1990. The central theme of her laboratory is the role of endothelial progenitor cells (EPCs) and endothelial plasticity in angiogenic diseases and in the normal repair of the vasculature in vascular tumors, and, conversely, in normal repair of the vasculature.

Xi He, PhD
Professor of Neurology
Department of Neurology

Xi He received his PhD from the University of California, San Diego. He completed a postdoctoral fellowship at the National Institutes of Health. He is a Chang Jiang Guest Professor at Huazhong University of Science and Technology in Wuhan, China. He is a Pew Scholar in Biomedical Sciences, Klingenstein Fellow in Neuroscience, and a Keck Foundation Distinguished Young Scholar in Medical Research. Dr. He’s lab focuses on the study of Wnt signaling in development, cancer and stem cell biology.

Laurie Jackson-Grusby, PhD
Assistant Professor
Department of Pathology

Laurie Jackson-Grusby received her PhD in Genetics from Harvard University and completed a postdoctoral fellowship at the Whitehead Institute for Biomedical Research. She serves on the External Scientific Panel for the NIH Human Epigenome Project. She is a Sontag Foundation Distinguished Scientist. Her lab is a consortium member of the NHLBI Bench to Bassinet project. The Jackson-Grusby lab research objectives are understanding how pediatric tumors are influenced by stem cells and epigenetic mechanisms.

Jordan Kreidberg, MD, PhD
Associate Professor of Pediatrics, Nephrology

Dr. Jordan Kreidberg received his MD and PhD from Johns Hopkins University School of Medicine. He completed his internship at Boston Children’s Hospital and a postdoctoral fellowship at the Whitehead Institute. Dr. Kreidberg’s principal research goal is to understand the genetic mechanisms of organogenesis, with a focus on the urogenital system.

Louis Kunkel, PhD
Professor of Pediatrics
Director, Genomics Program

Dr. Louis Kunkel directs the Genetics Division at Children’s Hospital. He received his PhD in Biology from Johns Hopkins University and completed postdoctoral fellowships at the University of California, San Francisco, and at Boston Children’s Hospital. He is a Howard Hughes Medical Institute Investigator and a member of the National Academy of Sciences. Dr, Kunkel’s principal research focus is on understanding the basis for muscular dystrophies.
