Dr. Osheiza Abdulmalik

Research Associate-PhD

Dr. Abdulmalik’s research interests broadly encompass the hemoglobinopathies and red blood cell disorders, with particular focus on sickle cell disease and beta-thalassemia. Though both disorders are consequences of simple genetic mutations, the implications of these mutations are inherently complex, and include significant morbidities, lifelong challenges, reduced quality of life, and early mortality in patients; as well as substantial healthcare burden on families, caregivers, and society in general. Dr. Abdulmalik’s current research focuses on two modalities of countering disease pathophysiology. The first approach, in tandem with a multidisciplinary team of collaborators, utilizes medicinal chemistry and structural biology to design novel drugs that block the primary pathophysiology of sickle cell disease, i.e., the polymerization of sickle hemoglobin. He employs an array of in vitro and in vivo assays to investigate the efficacy and pharmacokinetic/pharmacodynamic properties of select candidate drugs. The second approach investigates mutations in the coding region of the therapeutic beta-globin gene variants, which would, in addition to replacing the defective gene, confer additional beneficial effects, such as countering hemoglobin polymerization.
