Dr Ngwa is the Director of Global Health Catalyst (GHC) at Brigham and Women's Hospital, Dana-Farber Cancer Institute, Harvard Medical School. The GHC is dedicated to catalyzing high impact international collaborations to eliminate global health disparities with a major focus on cancer. The work has led to many productive collaborations in global oncology research, education and care, and is helping shape the emerging field of global radiation oncology. Besides serving as faculty Director of the GHC, Dr Ngwa's work integrates research, clinical service, and teaching, with current focus on clinical translation of technologies/approaches that can increase access to quality cancer treatment including smart radiotherapy biomaterials (Tiny drones to Target cancer). The award-winning drone technology is designed to eliminate both local and metastatic tumors with minimal collateral damage or side effects. The drones can be employed to deliver different drug payloads (including immunotherapy drugs and cannabinoids) precisely to disease sites or targets, with greater therapeutic efficacy. In radiation Oncology, Dr Ngwa is leading international research efforts to introduce a new radiotherapy approach without the need of currently used margins, such as the clinical target volume.
