The five-member 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, together with his or her unique perspective, to the mission of the Stem Cell Program at Children's Hospital Boston.


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 Children's Hospital Boston, in 1990. The central theme of her laboratory is the role of endothelial progenitor cells (EPC) in vascular tumors, and, conversely, in normal repair of the vasculature. She and her colleagues have shown that EPC from blood can be used to create small diameter arterial blood vessels with long term patency and function in an animal model.

Xi He, PhD
Associate Professor
Department of Neurology
Xi He received his PhD degree from the University of California, San Diego. He completed a postdoctoral fellowship at the National Institutes of Health. He is a Guest Professor at the School of Life Science and Engineering at Tsinghua University in Beijing, 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 of Pathology
Laurie Jackson-Grusby received her PhD in Genetics from Harvard University working with Dr. Phillip Leder. She did postdoctoral work with Dr. Rudolf Jaenisch at the Whitehead Institute for Biomedical Research. Dr. Jackson-Grusby's lab uses embryonic stem cells to develop new transgenic animal models. The lab is focused on epigentic regulation and uncovering the mechanisms by which epigentic changes contribute to disease pathogenisis. The research is currently directed at how tumor formulation is modulated by DNA methylation.

Jordan Kreidberg, MD, PhD
Associate Professor of Pediatrics, Nephrology
Dr. Jordan Kreidberg received his MD and PhD from Johns Hopkins Univerity School of Medicine. He completed his internship at Children's Hospital Boston and a postdoctoral fellowship at the Whitehead Institute.

Louis Kunkel, PhD
Professor of Pediatrics
Director, Genomics Program
Dr. Louis Kunkel received his PhD degree in Biology from Johns Hopkins University and completed postdoctoral fellowships at the University of California, San Francisco, and at Children's Hospital Boston. He is a Howard Hughes Medical Institute Investigator and a member of the National Academy of Sciences.
