Planning with the CyberKnife® VOLO™ Optimizer: Hear from the experts

December 9, 2020

In this webinar the presenters will share their approach to planning brain metastases, lung tumors, and prostate tumors using the VOLO optimizer. This will be followed by a moderated Q&A session.


Tatsiana Reynolds, Ph.D., DABR, Minnesota Oncology, Minneapolis, MN

Tatsiana Reynolds is a medical physicist at MN Oncology, where she works with CyberKnife and is involved in all steps of treatment process, including simulation, planning, treatment delivery and quality assurance. She graduated from Belarussian State University with a bachelor’s degree in physics in 2006. One year later she came to the United States to pursue a graduate degree in physics (biophysics/nanotechnology).  She was awarded a PhD in physics from Clemson University in 2011. After spending one year at Cornell University performing postdoctoral research, she decided that her passion lies in medical physics and decided to continue her journey on this path. After graduating from Chicago University with postdoctoral certificate in medical physics and completing 2-year medical physics residency at the University of Minnesota, she accepted a medical physics position at MN Oncology, where she has been working for more than 5 years now. During her career Tatsiana has published 12 papers, 1 book chapter, 1 patent and has 31 conference presentations and posters.

Muhammed Ozeroglu, MS, DABR, Las Vegas CyberKnife, Las Vegas, NV

Muhammed “Oz” Ozeroglu graduated with a degree in Biochemistry Pre-med from the University of Oklahoma. In 1994 he joined the US Navy as a nuclear submarine officer. In 2005 Mr. Ozeroglu received an MS in medical physics from Uniformed Services University of Health Sciences and finished his naval career as department head of radiation oncology at Naval Medical Center San Diego in 2009. From 2009-2010 Mr. Ozeroglu worked at Pasadena CyberKnife Center in California, and since 2010 has been the CyberKnife physicist at Las Vegas CyberKnife.

Matthew Witten Ph.D., DABR, NYU Langone Hospital—Long Island, NY

Matthew Witten, PhD, DABR is the Chief Physicist in the Department of Radiation Oncology and the Director of the Division of CyberKnife Radiosurgery at NYU Langone Hospital—Long Island. He is a Clinical Associate Professor at the NYU Long Island School of Medicine. Dr. Witten is a co-founder and member-director of Witten Clancey Partners, a medical physics solutions company.
