Cristian Cotrutz, Ph.D. - complete profile

Medical Physicist

I believe in encouraging innovation in radiation oncology and stimulating the development of novel techniques and protocols that bring value in the battle against cancer. When people's lives and well being are in our hands, no effort should be considered overwhelming.
