Research Program:

Research in the Emery laboratory is focused on basic and translational research in the field of hematopoietic stem cell gene therapy. Area 1: The identification, characterization, and application of chromatin insulators in order to improve the efficacy and safety of recombinant virus vectors. This includes in part the use of genetic screens and informatics to identify potential insulators, the study of insulator activity on chromatin structure, and the development of novel tumor formation assays to study vector-related genotoxicity. Area 2: The development of lineage-specific recombinant viral vectors designed for the regulated, ex vivo expansion of red blood cells and megakaryocytes, and the testing of these vectors in mice. Area 3: The regulated expansion of cord blood stem/progenitor cells. Area 4: The use of large animal models for assessing viral vector-transduced hematopoietic stem/progenitor cells.
