Aviva Berkowitz

Aviva Berkowitz, MD


Aviva is a Radiation Oncology resident at Montefiore Medical Center/Albert Einstein College of Medicine. She received her medical degree at the Albert Einstein College of Medicine and completed her internship in Internal Medicine at Montefiore New Rochelle Hospital.

Her clinical and research interests include applications of stereotactic body radiation therapy and immunotherapy in the treatment of non-small cell lung cancer, hepatocellular carcinoma, and oligometastatic disease. As a member of the Radiosurgery Society Resident Committee, Aviva has led two resident-driven regional workshops, including a resident debate regarding emerging topics in radiosurgery. Dr. Berkowitz is the Chair of the Residents Committee.

Evan M. Thomas

Evan M. Thomas, MD, PhD


Evan Thomas is a resident in the UAB Department of Radiation Oncology. He help the position of Chair of the RSS Residents Committee upon its conception and is currently Co-Chair of the Committee. He was educated in Materials Engineering at Arizona State University, then received an M.S. in Nuclear Engineering from the University of California at Berkeley before returning to his home state of Alabama to complete PhD in Biomedical Engineering and then his M.D. As a side project during his graduate thesis, he became interested in radiosurgical treatment planning under the mentorship of John Fiveash.

His particular relevant expertise is in single-isocenter volumetric modulated arc therapy (VMAT) treatment planning and delivery for multiple metastases, which he has been studying for nearly a decade. Additionally, he worked in close collaboration with Varian Medical Systems during a postdoctoral research fellowship which resulted in implementation of the UAB single-isocenter methodology into the HyperArc platform and its successful benchmarking

More recently he has helped develop the UAB Movement Disorder Radiosurgery Program, which utilizes the first coneless, MLC-based linear accelerator delivery technique for functional radiosurgery applications as well as the UAB Cardiac Radiosurgery Program for ventricular arrhythmia. He has published a variety of papers within the radiosurgery field, and given an extensive array of lectures & webinars on radiosurgical treatment planning for multiple metastases. Some of his other additional research interests include novel applications of emerging technology within radiation oncology, health physics, and healthcare public policy.

Stephanie Yoon

Stephanie Yoon, MD


Stephanie Yoon is a resident physician in the Department of Radiation Oncology at University of California, Los Angeles. She graduated from Massachusetts Institute of Technology with a Bachelor of Science degree in Biology and Literature.

She earned her medical degree at Lewis Katz School of Medicine at Temple University and went onto completing her internship at Abington-Jefferson Health. She has interests in stereotactic radiosurgery (SRS), stereotactic body radiotherapy (SBRT), magnetic resonance-guided radiotherapy (MRgRT), functional imaging, and other advanced techniques in radiation therapy.

Julie Jiang

Julie Jiang, MD, PhD


Julie Jiang is a radiation oncology resident at Montefiore Medical Center. She completed a double major in Biomedical Engineering and Applied Mathematics & Statistics at the Johns Hopkins University.

Dr. Jiang then went on to obtain an MD and PhD in Biomedical Sciences at Albert Einstein College of Medicine. Dr. Jiang has given oral presentations at conferences including ESTRO and Association for Clinical and Translational Science. She has published in several journals, such as Oral Oncology and Journal of Gastrointestinal Oncology.

Amanda Rivera

Amanda Rivera, MD

Junior Faculty Advisor

Amanda is a Chief Resident in the department of Radiation Oncology at Montefiore/Albert Einstein College of Medicine. She completed her medical training at Jefferson Medical College (Sydney Kimmel Medical College) in Philadelphia and will be completing her Radiation Oncology residency training in June 2020.

Her research interests include use of SRS for both benign and malignant intracranial indications, as well as, SBRT in pancreatic adenocarcinoma. She has been involved in several investigational projects including a review of the RSSearch Pancreatic SBRT Registry analyzing outcomes and obesity metrics. Amanda is also leading ongoing projects in the areas of radiation proctitis, diversity enhancement and improving disparities in cancer outcomes, social media as a tool in Radiation Oncology awareness, and Brachytherapy. As a member of the RSS Resident Committee, she has led two resident driven regional workshops, including a resident debate regarding emerging topics in radiosurgery and is actively involved in the new RSS mentorship pathway initiative. She is looking forward to starting her career as a junior attending this fall.

Stephanie Schaub

Stephanie Schaub, MD

Stephanie Schaub, MD, is honored to be serving as an Advisor on the Radiosurgery Society (RSS) Resident Committee. Stephanie completed her internship in medicine at Brigham and Women"s Hospital and is a current Chief Resident at University of Washington.

Stephanie has authored or co-authored numerous peer-reviewed publications in the use of stereotactic body radiation therapy, proton therapy, clinical and imaging biomarkers for decision-analytics research, and functional imaging-guided radiation therapy for the management of a variety of solid tumors, including ongoing research to identify radiomic predictors of the tumor microenvironment in soft tissue sarcomas. She worked with the RSS Resident Committee team to develop the new RSS mentorship pathway and will relish seeing the strong relationships this pathway fosters in the years to come. Stephanie is looking forward to pushing the frontiers of precision oncology, including increasing the use of SRS/SBRT, in the field of Pediatrics and Sarcoma malignancies as an Assistant Professor at University of Washington starting Fall 2020.

Therese Y. Andraos

Therese Y. Andraos, MD

Committee Member

Dr. Andraos received her medical degree from the American University of Beirut. She spent 1 year in Houston as a postdoctoral research fellow at The MD Anderson Cancer Center. As a foreign medical graduate, it was invaluable to have had that research training experience.

Dr. Andraos worked on multiple research projects highlighting the role of radiation therapy in various disease sites including lymphoma, prostate cancer, and breast cancer. In January 2020, she was part of the Radiosurgery Society resident debate, and discussed SBRT monotherapy vs EBRT+LDR Boost in intermediate risk prostate cancer. More recently, during the COVID-19 pandemic, she was redeployed to cover the inpatient internal medicine floors. While it was a stressful time both mentally and physically, it reminded her of what originally attracted me to medicine. It allowed her to continue to improve my medical acumen and helped her understand the importance of treating the patient as a whole.

One of Dr. Andraos' future career goals is to develop a further understanding of the role and implications of radio-immunotherapy in cancer patients. She strives to explore this aspect of radiation oncology further as a member of the RSS resident committee. She believes that precision medicine is the future of our field, as it can offer more personalized treatment options tailored towards the diverse immune and genetic profiles of each individual patient. With the help of her colleagues on this committee, she also plans to explore options which may improve the outreach of the RSS not only to the professionals in the field, but to the general public as well.
