Post-Doctoral Fellow – Autonomous Low-Field MRI

Description

Position Overview:
The Laboratory for Accessible MRI, led by Prof. Sairam Geethanath at Johns Hopkins University, invites applications for a two-year Post-Doctoral Fellowship. The fellow will work on cutting-edge research focused on advancing low-field deep learning methods and implementing autonomous low-field MRI systems to ensure consistent scanner operation and maintain high-quality image acquisition. This project will demonstrate the steps required on the 0.05T scanner (available in the laboratory) to track structural brain changes at par with 3T performance. These innovations are expected to improve the accessibility and affordability of MRI technology globally.

Key Responsibilities:

• Tracking brain changes in youth at 0.05T:
  • Advance existing, in-house super-resolution reconstruction methods at 0.05T.
  • Advance existing in-house denoising methods at 0.05T.
  • Refine segmentation of brain tissue matters at 0.05T using FreeSurfer.
• Scan youths (10 – 17 years) at 0.05T and 3T to demonstrate advances
• Develop and implement autonomous operational strategies for low-field MRI scanners
  • Introduce interventions during scanning to guarantee SNR and magnetic field homogeneity limits
  • Mitigate certain artifacts such as motion, electromagnetic interferences, Gibbs ringing, and wrap-around.
• Test and validate developed methods on the available MRI scanners, including:
• • Two custom-built low-field MRI systems (0.26T and 0.35T).
  • A commercial prototype 50mT Halbach scanner.
• Collaborate with a multidisciplinary team of researchers and engineers.

Qualifications

Key Qualifications:

• Ph.D. in Medical Physics, Biomedical Engineering, Electrical Engineering, Computer Science, or a related field.
• Strong background in MR physics, including pulse sequence design, image reconstruction, and signal processing.
• Proficiency in deep learning techniques, with experience in applying machine learning to medical imaging.
• Experience working with low-field MRI or MRI system development is highly desirable.
• Strong programming skills in Python, MATLAB, or similar.
• Ability to work independently as well as in a collaborative research environment.

Application Instructions

Application Process:
Interested candidates should submit the following documents:

• A detailed CV.
• A cover letter describing your relevant research experience and career goals.
• Contact information for three professional references.

Vaccine Requirements

Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID-19 vaccine. The COVID-19 vaccine does not apply to positions located in the State of Florida. We still require all faculty, staff, and students to receive the seasonal flu vaccine. Exceptions to the COVID and flu vaccine requirements may be provided to individuals for religious beliefs or medical reasons. Requests for an exception must be submitted to the JHU vaccination registry. This change does not apply to the School of Medicine (SOM). SOM hires must be fully vaccinated with an FDA COVID-19 vaccination and provide proof of vaccination status. For additional information, applicants for SOM positions should visit https://www.hopkinsmedicine.org/coronavirus/covid-19-vaccine/ and all other JHU applicants should visit https://covidinfo.jhu.edu/health-safety/covid-vaccination-information/.

The following additional vaccine requirements may apply, depending upon your campus. Please contact the hiring department for more information.

The pre-employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre-employment physical exam except for those employees who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office.
