Research Abstract

Dr Ngwa's research is focused on clinical translation of technologies/approaches that can increase access to quality cancer treatment. This includes smart radiotherapy biomaterials (Tiny drones to Target cancer or nanoparticle drones) and PhytoMedicines. The award-winning drone technologies are designed to help eliminate both local and metastatic tumors with minimal collateral damage or side effects. The drones can be employed to sustainably deliver different drug payloads (including immunotherapy/chemotherapy drugs or cannabinoids) precisely to disease sites or targets, with greater therapeutic efficacy. This work leverages the abscopal effect and the biomaterials drone technology in research to significantly increase survival and quality of life for patients. Dr Ngwa is also the Director of the Global Health Catalyst, dedicated to catalyzing high impact collaborations and initiatives to reduce healthcare disparities, with focus on cancer and other non-communicable diseases.
