Job Opportunities

Postdoctoral Research Associate 
Department of Radiation Oncology at St. Jude Children’s Research Hospital

22 September 2022 


Outstanding candidates are invited to apply for a medical physics postdoctoral research associate position in the Department of Radiation Oncology at St. Jude Children’s Research Hospital. In this two-year position, you will benefit from world-class resources and exceptional training in a top-ranked research environment while helping to advance treatment options for children with cancer.


Research Focus


The primary focus of this postdoctoral research associate position is on using Big Data analytics tools to improve treatment planning techniques in radiation therapy. We are especially interested in understanding the relation between physical radiation exposures and long-term biologic effects. Research aims include the following:


• Contribute to data infrastructure efforts by validating and applying automatic structure contouring pipelines, analyzing and curating databases of clinical dose distributions, and using good data practices


• Investigate optimal parameters of novel image-analysis and data-mining methods to better understand their robust application to pediatric treatment data


• Apply novel image analysis and data-mining methods to curated datasets to better understand radiation therapy outcomes of children with cancer


• Investigate ways in which artificial intelligence may contribute to improving outcomes models


St. Jude offers a collaborative research environment and exceptional support for scientific discovery. The successful candidate will work closely with the principal investigators, computational scientists, and students in the research group. The postdoctoral research associate will interact with radiation oncologists, information technology support staff, clinical therapy and physics staff, and clinical scientists. Research activities will include data collection, image analysis, dosimetry comparisons with treatment planning systems and Monte Carlo calculations, and report and manuscript preparation. Opportunities to gain clinical experience in proton and photon radiotherapy physics may be made available pending adequate research progress.


Resources and Equipment


As part of the Department of Radiation Oncology, the postdoctoral research associate will have access to abundant resources, including the world’s first proton therapy center with pencil-beam scanning technology that is designated solely for treating pediatric cancer, a detector-based spectral CT scanner, state-of-the-art 1.5T and 3T MR scanners, and a digital PET/CT scanner. The department also has a full suite of radiation oncology software, including Eclipse, RayStation, and Pinnacle treatment planning systems, MiM Maestro, and ProKnow analytics software.


Eligibility and How to Apply


Successful applicants will have a PhD or DSc degree in medical physics, biomedical engineering, radiological sciences, or other relevant engineering or physical sciences. The candidate should have excellent writing and speaking skills and strong knowledge and experience in analytical and scientific programming, with a preference for experience in MATLAB, Python, and/or C#.
