Dr. Djaoud received her DVM degree at the Higher National Veterinary School of Algiers. After obtaining a Master’s degree in Immunology from Paris Descartes University and Paris-Est Créteil University, Dr. Djaoud completed a PhD in Human Immunology at the University of Nantes, with Dr. Christelle Retière. During her doctoral work, Dr. Djaoud studied the human immunity to cytomegalovirus (CMV). She then pursued her research, as a post-doctoral fellow and a research scientist, in the laboratory of Dr. Peter Parham at Stanford University, where she made several important findings on the human immunity to herpesviruses and cancer. Dr. Djaoud’s current research at the University of Ottawa and the CHEO Research Institute investigates how specific human immune cell populations can efficiently kill herpesvirus-infected cells and cancer cells.
The Djaoud’s laboratory focuses on human innate lymphocytes and their diverse functional roles in viral infections, cancer and transplantation. The group is currently studying how herpesviruses and immunogenetics regulate innate immune cells through receptors for Human Leukocyte Antigen (HLA) class I, with a particular focus on γδ T cells and NK cells. Specifically, they study the effect of herpesviruses and polymorphisms in HLA and Killer cell Immunoglobulin-like Receptors (KIRs) on the repertoire formation of γδ T cells and other innate lymphocytes as well as their maturation and functional education. Their approaches combine functional immunology, T-cell receptor repertoire analysis and immunogenetics of HLA and KIRs. In order to study innate lymphocytes with ultra-resolution, the lab uses full spectrum flow cytometry, mass cytometry and high throughput gene sequencing.
