Research Studies

Dr. Tammuella Chrisentery-Singleton is an Assistant Professor of Clinical Pediatrics at Tulane University and is board certified in pediatric hematology/oncology. She will receive training under the mentorship of Cindy Leissinger, MD, Chief, Section of Hematology & Medical Oncology at Tulane University School of Medicine and Director of the Louisiana Center for Bleeding and Clotting Disorders. Chrisentery-Singleton graduated with honors from Xavier University, received her MD from Louisiana State University and then completed her pediatric residency at the University of Miami. Following residency, she completed pediatric hematology/oncology fellowship training at Johns Hopkins University, where she worked with Dr. Jim Cassella and developed a serious interest in disorders of coagulation, particularly hemophilia. After her fellowship training, she was recruited to join the pediatric hematology/oncology faculty at LSU and Children's Hospital of New Orleans. In 2010, Chrisentery-Singleton accepted a position at Tulane University because of her desire to receive more training and spend more time in the specialized coagulation medicine program. As an NHF-Baxter Clinical Fellow, she will receive dedicated training in bleeding and clotting disorders for both children and adult patients, along with mentoring in clinical research related to bleeding disorders. She will also continue her work on several ongoing clinical trials, and pursue her project in developing models to better determine pharmacokinetic parameters with a minimal number of needle sticks in pediatric patients with hemophilia. Her goals are to steadily improve her knowledge and skills in caring for patients with coagulation disorders, and continue building her academic career in coagulation medicine.

The goal of Dr. Chen's research is to examine a method for selectively expanding hematopoietic stem cells expressing the factor VIII transgene. She will also examine the immune consequences of this approach, based on the idea that gene transfer in platelets evades immune recognition. This research has the potential to elicit important clues to developing an approach for gene therapy of hemophilia A and hemophilia A with inhibitors.

Dr. Chen earned a PhD in hematology from Fujian Medical University in China. She already has more than 27 papers published in the Chinese medical literature. Her research in hemophilia and gene therapy will be under the mentorship of Dr. Qizhen Shi, MD, PhD, Associate Investigator at the Blood Research Institute and Assistant Professor of Pediatric Hematology at the Medical College of Wisconsin.
