Dr. Becker is an international expert in the GammaPod, a stereotactic radiosurgery technique for breast cancer treatment. His research spans radiosurgery, dosimetry, radiation safety, and image-guided therapy. He has collaborated globally on GammaPod installations and authored key publications on its clinical applications, dose optimization, and device commissioning.

His most recent work in Radiation Oncology explores dose homogeneity, brain metastasis treatment limits, and standardized dosimetry reporting to address reproducibility challenges in radiobiology. Earlier studies focus on prone breast positioning, linac collision avoidance, and stereotactic body frame transmission.

Scientific contributions include a 2014 NYU Institute Fellowship and an Editor’s Pick Award (2012). Dr. Becker’s publications highlight advancements in breast cancer treatment, radiation device safety, and reproducibility standards.
