Dr. Xenia Ray is an Assistant Professor and a member of the La Jolla Physics Team. A research-focused Physicist, she is the Associate Director of Adaptive Radiotherapy in the Center for Quality, Innovation, Value and Efficiency in Radiotherapy (QUIVER). She also serves as the Gynecologic Cancer Technology Service Chief for the Department.

Her research interests are focused on using the volumes of data generated by cancer centers to inform important clinical decisions surrounding patient care. Past projects included using radiomics features extracted from computed tomography images to predict non-small cell lung cancer outcomes, developing metrics to evaluate the performance of publicly available knowledge-based treatment models, and investigating the sensitivity of transit images to detect changes during treatment. She is currently developing an automated batch-processing framework to investigate the dosimetric gains possible with daily adaptive planning. This framework will provide quantitative data for when and how plans should be adapted using routinely acquired CBCT imaging, automated segmentation, and knowledge-based planning.

Dr. Ray is also an active clinical medical physicist in both external beam radiotherapy and brachytherapy. She is the Gastrointestinal (GI) Tumor Technology Section Chief and has an expanding role in resident education as a UCSD lecturer and rotation mentor.
