  • Rosa Bacchetta

    Rosa Bacchetta

    Associate Professor (Research) of Pediatrics (Stem Cell Transplantation)

    Current Research and Scholarly Interests In the coming years, I plan to further determine the genetic and immunological basis of diseases with autoimmunity or immune dysregulation in children. I believe that much can still be learned from the in depth mechanistic studies of pediatric autoimmune diseases. Genomic analysis of the patients' samples has become possible which may provide a rapid indication of altered target molecules. I plan to implement robust functional studies to define the consequences of these genetic abnormalities and bridge them to the patient's clinical phenotype.

    Understanding functional consequences of gene mutations in single case/family first and then validating the molecular and cellular defects in other patients with similar phenotypes, will anticipate and complement cellular and gene therapy strategies.

    Agnieszka Czechowicz

    Assistant Professor of Pediatrics (Stem Cell Transplantation)

    Current Research and Scholarly Interests Dr. Czechowicz’s research is aimed at understanding how hematopoietic stem cells interact with their microenvironment in order to subsequently modulate these interactions to improve bone marrow transplantation and unlock biological secrets that further enable regenerative medicine broadly. This work can be applied across a variety of disease states ranging from rare genetic diseases, autoimmune diseases, solid organ transplantation, microbiome-augmentation and cancer.

  • Daniel Dever

    Daniel Dever

    Instructor, Pediatrics - Stem Cell Transplantation

    Bio Dr. Daniel Dever is a Research Instructor in the laboratory of Dr. Matthew Porteus at Stanford University, in the Department of Pediatrics, Division of Stem Cell Transplantation and Regenerative Medicine. He completed his PhD in molecular toxicology at the University of Rochester where he studied the mechanisms of the aryl hydrocarbon receptor in mediating cerebellar transcriptional programs. During his postdoctoral work in the Porteus group, he (with others) developed a CRISPR/Cas9-based beta-globin (HBB) gene editing by homologous recombination methodology (gene targeting) in CD34+ hematopoietic stem cells as a potential therapeutic strategy to treat severe sickle cell disease. Dr. Dever (along with collaborators) has now successfully used this methodology to efficiently target >15 genes in primary blood cells that are associated with hematopoiesis, hematopoietic genetic diseases, hematopoietic malignancies, or safe harbor sites. Dr. Dever's primary research interests are to continue to leverage CRISPR/Cas9-based genome editing technologies to study the molecular mechanisms of gene targeting in human hematopoietic stem cells with the ultimate goal of optimizing and further developing novel cell and gene therapies for disease of the blood and the immune system. Currently, he is leading IND-enabling preclinical efficacy, feasibility, safety and tumorigenicity studies for FDA approval of a first-in-human clinical trial at Stanford in 2018 for the treatment of severe sickle cell disease using CRISPR/Cas9-based HBB gene targeting in autologous hematopoietic stem cells.

  • Natalia Gomez-Ospina

    Natalia Gomez-Ospina

    Assistant Professor of Pediatrics (Genetics) and of Pediatrics (Stem Cell Transplantation)

    Current Research and Scholarly Interests Dr. Gomez-Ospina is a physician scientist and medical geneticist with a strong interest in the diagnosis and management of genetic diseases.

    1) Lysosomal storage diseases:
    Her research program is on developing better therapies for a large class of neurodegenerative diseases in children known as lysosomal storage disorders. Her current focus is on developing genome editing of hematopoietic stem cells as a therapeutic approach for these diseases beginning with Mucopolysaccharidosis type 1 and Gaucher disease. She established a genetic approach where therapeutic proteins can be targeted to a single well-characterized place in the genome known as a safe harbor. This approach constitutes a flexible, “one size fits all” approach that is independent of specific genes and mutations. This strategy, in which the hematopoietic system is commandeered to express and deliver therapeutic proteins to the brain can potentially change the current approaches to treating childhood neurodegenerative diseases and pave the way for alternative therapies for adult neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease


    2) Point of care ammonia testing
    She also works in collaboration with other researchers at Stanford to develop point-of-care testing for serum ammonia levels. Such device will greatly improve the quality of life of children and families with metabolic disorders with hyperammonemia.

    3) Gene discovery
    Dr Gomez-Ospina lead a multi-institutional collaboration resulting in the discovery of a novel genetic cause of neonatal and infantile cholestatic liver disease. She collaborated in the description of two novel neurologic syndromes caused by mutations in DYRK1 and CHD4.

  • Melissa Mavers

    Melissa Mavers

    Instructor, Pediatrics - Stem Cell Transplantation

    Bio I am a physician scientist at Stanford University/Lucile Packard Children’s Hospital, with a clinical and research focus in stem cell transplantation. Prior training includes earning MD and PhD degrees through the combined program at Saint Louis University School of Medicine, where I investigated the role of the cyclin dependent kinase inhibitor p21 in suppression of inflammatory cytokine production and treating inflammatory diseases. This project led to the publication of two first-author peer-reviewed articles, several middle-author publications, and a significant review article. I subsequently completed Pediatrics residency at the University of California Los Angeles/Mattel Children's Hospital and Pediatric Hematology/Oncology Fellowship at Stanford. Currently I'm an Instructor of Pediatrics in the division of Stem Cell Transplantation and Regenerative Medicine.

    My long-term career goal is to develop a research program focusing on immune tolerance in stem cell transplantation and become a leader in the development of improved therapies for preventing or treating graft-versus-host disease. As such, I am excited about my ongoing work in the laboratory of Dr. Robert Negrin, focusing on the expansion and functional enhancement of regulatory T cells and invariant natural killer T cells. This work is currently supported by a St. Baldrick’s Foundation Fellowship, and has previously received funding from the Stanford Child Health Research Institute.

  • Robertson Parkman

    Robertson Parkman

    Adjunct Professor, Pediatrics - Stem Cell Transplantation

    Bio My principal research interests have been the assessment of the immunological consequences of hematopoietic stem cell transplantation including both acute and chronic graft versus host disease and immune reconstitution and the use of hematopoietic stem cell transplantation to treat genetic diseases. My laboratory was the first to suggest that chronic graft versus host disease was an autoimmune disease directed at histocompatibility antigens shared by donors and recipients. The observation leaded to the assessment of the role of thymic dysfunction in the pathogenesis of chronic graft versus host disease. As a pediatric immunologist I have investigated the role of hematopoietic stem cell transplantation initially in the treatment of primary immune deficiency diseases and later the treatment of metabolic diseases, which lead to my involvement in the early gene transfer clinical trials.
