Varian Advanced Oncology Solutions Therapeutic Medical Physics Residency Program

About

Varian's Advanced Oncology Solutions (AOS) is actively recruiting candidates for our two-year therapeutic medical physics residency program. Following our recent acquisition of Aspekt Solutions and its renowned residency program, we are thrilled to offer exceptional opportunities at five distinguished sites. Join us in shaping the future of cancer care.

  • Site 1: Memorial Hermann Health System — Houston, TX
  • Site 2: Missouri Baptist Medical Center — St. Louis, MO
  • Site 3: City of Hope-Atlanta: Newnan, GA
  • Site 4: City of Hope-Chicago: Zion, IL
  • Site 5: City of Hope-Phoenix: Goodyear, AZ

The residency program is two years in duration. The intent of the program is to train individuals who have elected to pursue a career as a clinical medical physicist in community practice. The program will offer a practical and varied educational experience including training opportunities with a diverse set of equipment and treatment modalities.

Applicants must have obtained a graduate degree from a CAMPEP-accredited medical physics graduate program. Eligible candidates will need to have completed their graduate requirements prior to employment as a resident in the program. Both MS level and PhD level applicants will be accepted. There are two ways to apply for the Varian AOS Therapeutic Medical Physics Residency Program. Applicants are welcome to apply through the AAPM Medical Physics Residency Application Program (MP-RAP), which matches applicants to potential residency programs, or directly. Candidates are encouraged to submit their applications early as the number of eligible candidates is expected to exceed the number of interviews that can be granted.

Required to Apply

Candidates must also have the necessary paperwork to work in the United States.

Applying for the Residency Program

Varian Advanced Oncology Solutions (AOS) will be accepting resident applications once it receives CAMPEP accreditation. AOS will accept residents through the Match Program and will accept residents outside of the Match program.

Frequently Asked Questions

What is Varian Advanced Oncology Solutions?

Varian is a leader in the oncology space with products, software, and services. Advanced Oncology Solutions (AOS) harnesses the power of technology and clinical expertise to furnish cancer care providers with a wide range of services that help support, enhance, and expand operations and improve outcomes for patients.

Where are the residency positions located?

Varian AOS currently is establishing five clinical residency sites:

  • Site 1: Memorial Hermann Health System — Houston, TX
  • Site 2: Missouri Baptist Medical Center — St. Louis, MO
  • Site 3: City of Hope-Atlanta: Newnan, GA
  • Site 4: City of Hope-Chicago: Zion, IL
  • Site 5: City of Hope-Phoenix: Goodyear, AZ

Residency sites are selected based on adequate equipment resources, patient workload, and mentor resources.

How long is the residency?

The Varian AOS residency lasts two years. Many residents will start on July 1 of each year. This is to be consistent with AAPM’s match program timeline. Residents that are accepted outside of the match may start at a time other than July 1, but efforts will be made to start the resident at a logical time within the program schedule. The purpose of the residency program is to train residents to become clinical medical physicists. We have divided the two-year program into several 3-month rotations, including:

  • Clinical patient management
  • Imaging
  • Patient Simulation
  • Contouring and treatment planning
  • Patient QA
  • Treatment delivery
  • Special procedures to include SRS, SRT, and SBRT
  • Radiation Instrumentation
  • Radiation safety
  • Brachytherapy
  • Clinical program development
  • IS/EMR

For each area, residents will read specified publications, acquire new skills, complete a project, and pass an exam that assesses mastery of the topic. All 3-month rotations are performed at the clinical site. (Details are listed in the residency handbook).

Does the program take MS candidates or PhD candidates?

The Varian AOS Therapeutic Medical Physics Program accepts both MS and PhD candidates. The residency program does not have a third year focused on research. The program is ideal for the candidate who is interested in becoming a clinical medical physicist. Although there is not a third year dedicated to research, residents will have opportunities to engage in small physics research projects. These projects are typically oriented towards new technologies, new procedures, and data analytics. Varian AOS will support residents financially to attend regional and annual association meetings.

What is the interview process?

Varian AOS will participate in the AAPM common residency application, but candidates may also apply directly. Resident applications are reviewed in January of each year. Resident applications are evaluated, and virtual interviews are scheduled for the top candidates. These virtual interviews typically take place using videoconferencing tools like Teams, Zoom, or equivalent. Top applicants from the video interviews are scheduled for a virtual on-site interview. Virtual on-site interviews will be conducted. These will typically occur in March. Varian program leadership will either be on-site or available virtually during the on-site interviews. The candidate will have the opportunity to meet the program director, associate program directors, physics mentors, and program administrators. At the conclusion of all interviews, AOS will submit the top candidates to the AAPM National Match Program. Varian will pay up to $2,000 for relocation expenses.

Residents may enter the AOS residency program outside of the match. The interview process will follow the same process but may be on a different timeline. Varian AOS will determine the ideal time for a resident outside of the match to start the two-year program.
