Radiation ― A Double-Edged Sword

Radiation is a well-known carcinogen to humans, yet it remains valuable for diagnosis and treatment. To understand the mechanisms underlying radiation-induced effects on human health, we are conducting cutting-edge research using a variety of approaches, including microbeams, animal models, and large-scale cohorts. Our goals are to develop innovative radiotherapeutic technologies and to establish personalized radiation risk assessments.
