Radiation ― A Double-Edged Sword

Radiation is a well-known carcinogen to humans, yet it remains valuable for diagnosis and treatment. To uncover the molecular mechanisms behind this double-edged effect on human health, we are conducting cutting-edge research using a variety of approaches, including microbeams, animal models, and large-scale cohorts. Our overarching aim is to both develop next-generation radiotherapeutic technologies and establish personalized systems for assessing radiation risk.
