Cristian is a Radiobiologist who specializes in understanding the effects of Synchrotron Radiation to use it as a novel treatment for cancer. He currently works at the Institute of Anatomy of the University of Bern in Switzerland. Cristian collaborates with the European Synchrotron and the Australian Synchrotron to produce rectangular parallel microbeams of 25-50 um of Synchrotron light, which are spaced by 200-400 um. This configuration increases the normal tissue tolerance to the radiation treatment while directly targeting the tumor.
Previous to this appointment, Cristian spent 6 years working towards understanding the effects of Synchrotron Radiation in normal brain tissue after Experimental Brain Radiotherapy using Synchrotron Radiation. Within this topic, he studied Radiation-Induced Bystander Effects in-vivo and in vitro, DNA damage caused by Synchrotron radiation, and effects of low-doses of ionizing radiation, mainly: Low-dose hyper-radiosensitivity, increased radioresistance, and adaptive responses.
