Primary Duties And Responsibilities

• Patient Care: Perform and delegate patient-specific dosimetry tasks, ensuring safe and accurate radiation treatments. Work alongside radiation oncologists and physicists to support simulation, image processing, and treatment planning.. Participate and/or leads departmental chart reviews (patient care rounds).
• Treatment Planning: Responsible for most treatment sites and techniques. Collect and analyze patient data and design optimal approaches for treatments. Responsible for basic dose calculation and 3D, IMRT, SBRT, SRS/SRT. Support and evaluate the implementation of advanced treatment planning procedures such as SBRT/SRS and Adaptive RT. Interact with radiation oncologists to define target volumes and critical structures. Lead the implementation of new techniques and treatment modalities for radiation therapy.
• Leadership and Management: Serve as a key member of the dosimetry team. Collaborate on process improvements and strategic planning. Guide the dosimetrist group in integrating new technologies, including AI-assisted planning and remote dosimetry workflows. Participate in departmental quality improvement initiatives and committees.
• Teaching, Training, and Research: Provide or delegate training and educational support for dosimetry students, physician residents, physics residents, and radiotherapy students. Keep the dosimetry team informed of departmental policies, procedures, and innovations. Help train new staff. Assist in national accreditation process for the department. When appropriate, participate in research and development projects in collaboration with faculty members. Participate in clinical research and data submissions for clinical trials and national protocols.
