Lisa Pullens, RN, BSN, CPHN

Lisa received her RN-BSN 33 years ago at Mount St. Mary’s College in L.A. and has been working in paediatrics since her junior year in school. At Children’s Hospital L.A., she received a great deal of training and mentoring, working in rehab, ICU and other areas. She also gained additional paediatric ICU experience at Huntington Hospital in Pasadena, California. She is a haematology/haemophilia/ sickle cell nurse coordinator. She coordinates patient care and provides teaching to patients and families. She also facilitates patient and family appointments and follow-up and takes part in their clinic visits. For the last 22 years, she has been working with the same haematologist, Dr. Nadia Ewing. They had a freestanding haematology practice near Huntington Hospital in Pasadena and then relocated to City of Hope almost 17 years ago. It was quite a transition for her, from her acute care experience to the chronic illnesses that they treat in their practice. They specialize in non-malignant haematology, including bleeding/clotting disorders, sickle cell disease and other hematologic disorders. They work with individuals ranging from birth to about 27 years of age. Online profile

Z. Jim Wang, PhD

Dr. Wang is a professor of pharmacology and university scholar at the University of Illinois, Chicago. He is associated with various departments and centres of the university such as Department of Biopharmaceutical Sciences, Center for Biomolecular Sciences, Program for Collaborative Research in the Pharmaceutical Sciences, Cancer Center and Sickle Cell Center. A major objective of his laboratory is to understand the mechanisms leading to chronic pain, opioid tolerance and addiction, and opioid-induced hyperalgesia. He is also interested in developing new therapeutic targets as well as novel drugs that can be used for the treatment of pain, where the focus of pain conditions are the pain in sickle cell disease, and chemotherapy-induced pain. Recently professor Zaijie Wang received a MIRA (R35) grant for $4.6M over seven years for a project, entitled "Molecular mechanism and targeting of chronic pain in sickle cell disease".   Representative Publications: PKCδ-targeted intervention relieves chronic pain in a murine sickle cell disease model. CaMKIIα underlies the spontaneous and evoked pain behaviors in Berkeley sickle cell transgenic mice. IL1A rs1800587 associates with chronic noncrisis pain in sickle cell disease. Dopamine D3 receptor Ser9Gly and catechol-o-methyltransferase Val158Met polymorphisms and acute pain in sickle cell disease.

Mark C. Walters, MD

Dr. Walters is the director of Bone Marrow Transplantation at UCSF Benioff Children’s Hospital Oakland. He has been the Director of Stem Cell Therapy and a Division leader since 1999. During this period, he expanded his responsibilities to develop a career in stem cell transplantation in sickle cell disease. The integration of these areas of expertise has enabled him to develop a national program focusing on novel therapies for blood disorders. Since joining Children’s Hospital, he has devoted his research career to pursuing curative therapies for hemoglobin disorders with an overarching goal of expanding this treatment more broadly to affected individuals. With NIH and industry support, he has conducted a number of multicenter clinical trials for sickle cell disease and thalassemia. Currently, he is focused on initiating early phase clinical trials to test novel genomic editing techniques in hematopoietic stem cells (HCT) from individuals affected by hemoglobin disorders, starting with a high-profile trial in sickle cell disease. Other projects in the pipeline include activation of fetal hemoglobin by genomic editing in stem cells. Online profile
