Sergei Zavgorodni is an Adjunct Professor at the University of Victoria, specializing in medical physics and radiobiological modeling. He holds a PhD and has extensive experience in Monte Carlo modeling and radiotherapy applications. His research primarily focuses on developing Monte Carlo methods for accurate radiotherapy dose calculations, particularly exploring their applications in advanced treatment deliveries such as intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT). Zavgorodni’s work includes contributions to the Vancouver Island Monte Carlo system, which provides automated Monte Carlo dose calculations for modern radiotherapy treatments. He has also published numerous papers in reputable scientific journals and has significantly involved graduate and undergraduate students in research projects, enhancing their learning experiences and contributing to important findings in the field. His research interests encompass the impact of treatment delivery errors on biological outcomes and the development of new radiobiological concepts such as the biological effective constant dose (BECD) and equivalent uniform stochastic dose (EUSD). Throughout his career, Zavgorodni has made substantial contributions to national and international conferences, showcasing the results of his research and the involvement of students in the scientific community.
