About Niwanthi

Dr. Niwanthi Rajapakse serves as Senior Lecturer in Biomedical Sciences in the School of Biomedical Sciences, Faculty of Health, Medicine and Behavioural Sciences at the University of Queensland. She earned a Bachelor with Honours and a Doctor of Philosophy from Monash University. Her research specializes in cardiorenal disease, cardiovascular disease, heart failure, kidney disease, kidney failure, and nitric oxide bioavailability. As leader of the Rajapakse Group in cardiorenal research, she examines mechanisms of cardiorenal syndrome pathogenesis, including reduced nitric oxide bioavailability and inflammation contributing to renal disease in heart failure. Her work explores novel therapeutic approaches to restore nitric oxide production, the role of L-arginine transporters, microbiome influences in cardiorenal syndrome, and factors affecting nitric oxide pathways. Rajapakse has contributed to understanding renal oxidative stress, gut microbiota effects on hypertension and heart failure, and impairments in the L-arginine-nitric oxide pathway in hypertension and diabetes.
