I'm a medical researcher and biologist based in Tunisia, primarily affiliated with the Department of Hematology at Tunis El Manar University and La Rabta Hospital in Tunis. My research is centered on Biological Hematology, with a strong focus on diagnostic biomarkers, coagulation disorders, and blood-related pathologies. My academic work focuses on improving diagnostic accuracy and clinical outcomes in hematology through the following areas: Hemostasis and Coagulation: I've conducted extensive research on D-dimers, particularly their role in diagnosing venous thromboembolism (VTE) and their prognostic value in COVID-19 patients. Hematological Malignancies: My work includes studying the diagnostic thresholds for lymphocytosis (distinguishing between clonal and reactive states) and researching conditions like Multiple Myeloma and chronic lymphocytic leukemia. Platelet Disorders: I investigated the accuracy of different platelet counting techniques (impedance vs. optical) in patients with microcytic anemia. Clinical Biomarkers: A significant portion of my research involves evaluating ratios such as the Neutrophil-to-Lymphocyte Ratio (NLR) and Platelet-to-Lymphocyte Ratio (PLR) as diagnostic or prognostic tools in various inflammatory and hematological conditions. Anemia and Rare Deficiencies: I have published case studies and research on autoimmune hemolytic anemia, thalassemia, and acquired factor XIII deficiency.
