Medical Physics Therapy Residency Program

The Jefferson Center City Radiation Oncology Department has two Elekta Versa and three Varian Truebeam linear accelerators, four with six degree of freedom couch motion. Additionally, the department has a Viewray Systems MRIdian MR-guided linac, a Siemens SomatomGO Dual Energy CT simulator, and a Nucletron Flexitron HDR remote afterloader. We use Mosaiq and Aria R&V, Eclipse, Brainlab, MIM, and Oncentra treatment planning systems. Special procedures include SBRT, TBI, TSET, SRS, HDR (gyn, prostate, and skin), radioactive microspheres, radiopharmaceutical therapies and LDR implants with I-125 for eye plaques and CS-131 for recurrent head and neck cancer. Residents will also work with Cyberknife and Ethos machines, as well as LDR prostate implants located at enterprise Jefferson/CCHS locations.

The Jefferson - Center City Campus Physics Department has 14 clinical faculty physicists and a dedicated computational physicist. There are six dosimetrists and ten radiation oncologists, as well as several post-doctoral fellows and two physics assistants. In addition to the physics residency, the department provides education to radiation oncology residents, medical students, therapy and dosimetry students. Residents are given the opportunity and option to participate in clinical development and research in-line with the grant-funded work performed by Jefferson faculty. Recent resident projects include AI and machine learning, radiotheranostics, clinical trial research, novel image reconstruction algorithms, and functional imaging. Resident projects have resulted in oral presentations at national conferences (AAPM, ASTRO, ABS), publications in high-impact peer-reviewed research journals, and invention disclosures.

Jefferson - Center City Campus residents are hired at the PGY-1 level and receive the same benefits package as MD residents. More information is available at Jefferson Resident Benefits.

Interviews for Jefferson-Center City positions will take place REMOTELY, tentatively scheduled for February 11 and 12, 2026 with ~10-15 applicants per day. Invited candidates will have the opportunity to visit the clinic for on-site tours in March.

Located in Philadelphia, PA, the department is easily accessed by public transportation within the city and from the nearby Pennsylvania and New Jersey suburbs. Philadelphia is one of the most diverse cities in the country, with historic attractions, a delicious global food scene, thriving music and arts communities, and countless unique neighborhoods to explore. We are about an hour from the Pocono mountains for hiking and skiing, and less than two hours from the ocean at the Jersey Shore. 

Jefferson is an Equal Opportunity Employer and values diversity and encourages applications from women, members of minority groups, LGBTQ individuals, disabled individuals, and veterans. Jefferson-Center City is currently able to support residents with J1, TN, and F1 OPT-STEM extension visa. Requirements must be confirmed prior to interview.

The ChristianaCare Health System (CCHS) Radiation Oncology Department is in Newark, DE, at the Helen F. Graham Cancer Center and Research Institute, an NCI Community Oncology Research Program. As the largest healthcare provider in the smallest state in the union, CCHS treats, on average, 160 patients daily via external beam therapy and brachytherapy. Christiana has five Elekta linacs, 1 Cyberknife, one Varian Adaptive Ethos with Identify for gating, 1 Flexitron HDR unit, and 3 CT-simulators. The Elekta accelerators have VisionRT for gating, 4D-CBCT, intrafraction CBCT and Hexapod 6DOF depending on location. The primary planning and EMR are Raystation and MOSAIQ but Eclipse, Aria, Accuplan and ETM planning are used for specialty machines. SRS, SBRT, and VMAT-TBI are on site advanced procedures at CCHS. The Brachytherapy program has multiple cases every week, including a prostate permanent seed implant program with I-125 and P-103 and Gyn HDR cases. Hands-on experience with TSET, standard Varian linacs, and a ViewRay MRIdian linac is provided through the affiliation with Jefferson-Center City. The advantages of this Jefferson-ChristianaCare affiliation include the ability to share equipment, software and expertise between the two prestigious departments, as well as providing a larger group of residents and faculty with knowledge exchange, networking, and socializing.  

The CCHS physics department has nine full-time clinical physicists sharing the support of all clinical programs, software and commissioning under the leadership of the Chief Physicist, Laura A. Doyle, PhD. This group exceeds average AAPM minority ratios for gender and Asian minorities. Our professional experience and education vary, from new post-residency hires to thirty years of experience, boarded and non-boarded, with Masters and PhD degrees. There are 9 dosimetrists and ten radiation oncologists, as well as a physics and dosimetry assistant. Christiana is a clinical training location for both therapists and dosimetrists, as well as a rotation site for the Jefferson Radiation Oncology Residency. 

Christiana physicists participate in clinically relevant research resulting in local research awards, presentations at national conferences, and publications in peer-reviewed research journals. Recent efforts have included 3D printing, AI contouring, integrated CSI feathering, and responding to cybersecurity attacks.  We are an engaged group of physicists, working towards the advancement of our profession while providing high quality clinical care to our patients. Our team has decades of clinical, educational, and mentoring experience and enjoys teaching, exploring, and learning with our residents. We welcome the opinions and experience of our medical physics residents as part of our clinical team.  And while we are a large, busy clinical department, we operate with an efficiency such that we generally finish treatments early, allowing early access to the machines for completion of evening quality assurance, which fosters a healthy work life balance.

CCHS offers full benefits for residents under the AGCME supervision for the hospital. This includes PGY-1 salary for first year residents, sick and vacation time, and health, vision, and retirement benefits. More information can be found at CCHS Resident Benefits.

Interviews for the CCHS position will take place REMOTELY, tentatively scheduled for Friday, February 6, 2026. Invited candidates will have the opportunity to visit the clinic for on-site tours in March.

ChristianaCare Health System, located in Newark, DE, is less than one hour from Philadelphia, and two hours from Washington, D.C. and New York City, NY. From here, one can easily access mountains for hiking and skiing, or the ocean for swimming and surfing. Our first-floor location within a community cancer center allows for natural lighting throughout the department, creating an ideal work environment, easy access to parking, and bucolic campus walking trails. CCHS is an Equal Opportunity Employer and values diversity, and encourages applications from women, members of minority groups, LGBTQ individuals, disabled individuals, and veterans. At this time, we are unable to provide visa support for residents. 

Jefferson Asplundh Cancer Pavilion, a state-of-the-art 86,000 sq. ft. comprehensive cancer center, opened in 2018. Technology includes three Varian Truebeam linear accelerators (two with 120 MLC and one Edge with 120 HD-MLC, Vision RT). There is a Siemens Definition CT simulator with RGSC capabilities. An on-campus imaging center provides MRI and PET/CT capabilities. Special procedures include IMRT/VMAT, SRS, and SBRT, with planning performed in Eclipse and Mosaiq R&V. The department also has an active Nucletron Microselectron HDR program using Oncentra CT/MR volume-based planning. Asplundh residents will also work with Cyberknife, Ethos and Viewray Systems MRIdian machines, as well as LDR prostate implants, TBI, and TSET located at enterprise Jefferson/CCHS locations.

The Jefferson-Asplundh physics division has four physicists, three radiation oncologists, and three dosimetrists. In addition to the physics residency, the division provides education to radiation oncology residents, medical students, therapy and dosimetry students.
