The overall objective of the Core Center for Excellence in Hematology (CCEH) is to support investigators by providing access to unique sets of reagents, resources, technical expertise and equipment that are either unavailable or cost-prohibitive at the Center. Cell Processing Core B offers the ability to obtain large quantities of specific enriched cell populations, such cells are being used to help define the molecular and functional properties that make hematopoietic stem cells unique, and to elucidate the role of other blood cell populations in engraftment, disease control, and graft-versus-host complications. In my role as Scientific Director of the Center's Clinical Cell Therapy Laboratory and the cGMP Therapeutic Manufacturing Facility, a position I have held for over 10 years, I have a very strong appreciation for quality control, quality assurance, and compliance with regulations. I also direct several research based cores, ranging from specimen repositories to multi-parameter flow cytometry to large-scale cell processing. I have been using/developing various cell sorting techniques for over 25 years, starting as a graduate student at UC Irvine through post-doctoral training at Stanford with Irv Weissman to high-speed FACS at SyStemix to the first FDA-approved CD34 selection device at CellPro. Those previous experiences, along with my current research and clinical responsibilities, have emphasized the need for teamwork, collaboration, and cooperation to help advance scientific understanding. The CCEH model continues to build on those same values by providing high quality support services to the research community. Under my leadership as Core Director, the CCEH Cell Processing core has experienced tremendous growth, supported investigators from all over the country, and contributed to a very extensive number of publications. I look forward to continuing to provide such services and be able to assist researchers in their basic science, pre-clinical, and therapeutic studies.

I have a broad range of research interests, with a particular focus on the development of improved therapeutic strategies using various human stem cell populations. My long-term goals for this area are to identify better markers for the characterization of stem and progenitor cells, to improve the isolation technologies for enriching these types of cells, and to develop ex-vivo manipulation strategies that can enhance the therapeutic potential of these cells.
Another primary research area will involve studying human dendritic cell populations. I am interested in exploring the differential mobilization of distinct dendritic precursor subsets in response to specific manipulations such as cytokine treatment, the identification of unique markers to enrich those types of cells, and the ex-vivo generation of dendritic cells from precursor populations. These dendritic cells will then be manipulated to either enhance specific immune responses (e.g. anti-tumor or anti-viral activity) or dampen down inappropriate reactions (e.g. GVHD, automimmune disease, tolerance induction).
All of these research goals have a therapeutic clinical focus, and will ultimately involve the 'engineering' of patient grafts to investigate the role of specific cell populations in transplantation outcomes. This ties in directly with the Center's Cellular Therapy Laboratory and the new cGMP facility, and the role these units will play in manipulating blood and bone marrow components for the treatment of patients. It has become clear that the FDA is becoming more involved in overseeing this area of graft engineering and intends to tightly regulate this field. Thus, another goal of mine is to become very proficient in GLP, GTP and GMP regulations, both to help the Center moveforward in the development of its therapeutic strategies, and to facilitate the interactions with the FDA in this rapidly evolving area.
