About The Position

Mary Bird Perkins Cancer Center is seeking a Therapy Medical Physicist to join its Baton Rouge, Louisiana team in a full-scope clinical therapy physics role. The physicist will share responsibility for treatment-planning quality, machine and patient-specific quality assurance, SRS and SBRT, motion-managed treatments, regulatory and accreditation compliance, and acceptance and commissioning of technology across a multi-site cancer program. The role works alongside a team of approximately fifteen physicists and residents using a modern Elekta fleet. A central focus is helping launch CBCT-guided online adaptive radiation therapy across the C-arm linac fleet using Elekta Evo and the Elekta ONE Online adaptive platform. The physicist will commission the platform, validate auto-segmentation and synthetic-CT dose accuracy, develop policies and procedures, and serve as an adaptor at the console. The role also supports treatment delivery on the Elekta Unity MR-linac. The balance of adaptive work and broader clinical service will be shaped around the physicist’s interests and program needs. The position offers opportunities to lead research, mentor residents in a CAMPEP-accredited Medical Physics Residency Program, contribute to graduate education with LSU, and participate in Physics DevOps, an in-house clinical and administrative software development program. Applications are welcomed from experienced adaptive physicists and strong recent graduates of CAMPEP-accredited residencies; the role may be structured to support an early-career physicist.

Requirements

M.S. or Ph.D. in Medical Physics from a CAMPEP-accredited program, or a Ph.D. in Physics with equivalent medical physics training.
Completion of a CAMPEP-accredited residency in Therapeutic Medical Physics.
ABR certification in Therapeutic Medical Physics, or board eligibility with a clear path to certification.
Eligibility for licensure as a Medical Physicist in Louisiana.
Exceptional analytical, communication, and problem-solving skills.
Sound and timely clinical judgment under real-time conditions.
Ability to work effectively both independently and collaboratively with therapists, dosimetrists, and physicians.
Passion for continuous learning and clinical excellence.

Nice To Haves

Online adaptive experience, such as Elekta ONE/Unity, Varian Ethos, or equivalent; console adaptor experience is of particular interest.
Proficiency with Monaco or a comparable treatment-planning system.
SRS/SBRT experience.
Experience with multi-site clinical operations and regulatory compliance.
Scripting or software development experience, particularly Python.
Strong recent graduates of CAMPEP-accredited residencies are encouraged to apply.

Responsibilities

Serve as physicist-adaptor in online adaptive workflows on C-arm linacs and the Unity MR-linac, including reviewing and editing auto-generated contours, overseeing on-table re-optimization, evaluating and selecting plans, independently verifying dose, and clearing verification imaging before beam-on.
Lead acceptance testing, commissioning, and clinical release of adaptive planning and delivery systems, including validation of deformable registration, site-specific auto-segmentation models, and CBCT/synthetic-CT dose calculation accuracy.
Develop and maintain adaptive-specific quality assurance, including end-to-end testing, periodic QA of the adaptive chain, and independent monitor-unit verification methodology for adapted plans consistent with AAPM TG-219.
Perform and oversee routine and non-routine linac QA, patient-specific QA, and annual regulatory testing across the treatment fleet.
Provide physics support for SRS, SBRT, and hypofractionated treatments, including motion management and DIBH workflows.
Oversee treatment-planning quality in Monaco, including plan review, complexity surveillance, and secondary dose calculation.
Conduct risk analysis and process mapping for new workflows using FMEA methodology per AAPM TG-100.
Ensure compliance with applicable regulatory and accreditation standards and support the department’s accountability for technical and regulatory performance.
Contribute to technology evaluation, selection, and installation.
Train and mentor therapists, dosimetrists, and physician colleagues on adaptive workflows and new technology.
Participate in the departmental after-hours and weekend physics call rotation.
Pursue research in adaptive radiotherapy, dose accumulation, plan complexity, and treatment automation.
Mentor medical physics residents and guide research projects toward publication-ready standards.
Contribute to graduate education through teaching, curriculum development, or course direction with LSU.
Contribute to Physics DevOps, the in-house software development program.
Engage with the medical physics community through AAPM, ASTRO, professional society service, and conference participation.
Pursue continuing professional development to maintain certification and licensure.
