  • Summary

    The Department of Radiation Oncology at St. Jude Children’s Research Hospital is seeking a post-doctoral associate to provide support for physics research focused on proton range-based registration and proton range verification through phantom and patient studies and data acquisition, analysis and model improvement. Publishing research papers is an expectation. The duration of the postdoctoral research associate assignment is two years, effective July, 2018.


    Research Focus

    The aim of proton range-based registration is to mitigate proton range uncertainty caused by daily patient positioning and body anatomic changes. The goal of proton range verification is to improve the verification accuracy in clinical scenarios with and without range-based registration.


    St. Jude offers a highly collaborative research environment as well as exceptional support for scientific discovery. The candidate will work closely with the supervisor/mentor, group members, clinical therapy and physics staff, radiation oncologists, lT support staff and other staff. Opportunities to gain clinical experience with available systems will be provided.


    Resources and Equipment

    The St. Jude Red Frog Events Proton Therapy Center is the first proton therapy center in the world dedicated solely to the treatment of children with cancer. The proton center has a synchrotron-based proton pencil beam scanning system. The system includes two gantry rooms and one fixed beam room; the latter is equipped with a mini pencil beam scanning system. The center has the most accurate patient positioning systems including camera-assisted robotic positioning and gantry-independent robotic kV CBCT.


    The department has a wide range of state of the art imaging systems for treatment planning and adaptive therapy that will be used for proton range verification. These systems include two MRI units (1.5T and 3T) and a multi-layer detector spectral CT. A digital PET/CT will be used for proton range verification.  The department houses two photon linear accelerators with MV-CBCT systems. A high-dose-rate brachytherapy afterloader is equipped with a digital fluoroscopy unit. A full range of state of the art radiation measurement equipment and specialized phantoms are available. The department uses a variety of treatment planning systems supporting the research.

    Minimum Education

    Qualified candidates must have a PhD in Medical Physics, Physics or Engineering related to Medical Physics, and demonstrate experience in numerical analysis with Matlab and/or c/c++ programing. Experience with Monte Carlo simulation, GPU and itk programing is preferred.
