Post-Doctoral Fellowship in Advanced MR Spectroscopy Faculty

Overview

The research group led by Dr. Georg Oetlzschner at The Johns Hopkins University School of Medicine invites applications for a two-year Postdoctoral Fellowship. The fellow will work on NIH-funded research projects focused on developing novel data processing and analysis methods for in-vivo MR spectroscopy (MRS) and their application in the human brain. The goals are: (i) to improve reliability and reproducibility of in-vivo MRS metabolite concentration estimation;

(ii) to demonstrate their utility as biomarkers of function and disease; (iii) to disseminate new methods to researchers worldwide through our collaborative open-source MRS analysis software platform, "Osprey".

• Advance our newly-developed general linear-combination model.
• Develop appropriate quantitative metrics to evaluate which model is best (quantitative information criteria).
• Develop new sampling methods (based on Markov Chain Monte Carlo) to solve optimization problems and characterize the uncertainty of the modeling.
• Acquire MRS data in healthy volunteers, as well as patients with brain tumors and other disorders.
• Integrate the newly-developed methods for dissemination via the "Osprey" platform.
• Contribute to dissemination, maintenance, and user support of the "Osprey" platform.
• Beyond this, there will be opportunities to pursue goals such as:
• Develop new MRS/MRI pulse sequences.
• Develop new analysis methods to parametrize and model MRS artefacts such as lipid contamination (and/or eliminate).
• Develop deep-learning-based methods for processing and analysis.
• Develop novel quantification routines specifically suitable for pediatric and/or aging cohorts.
• The candidate is expected to:
• Work independently and as a constructive part of a large team of interdisciplinary researchers.
• Follow all key principles of responsible and reproducible research.
• Draft and submit manuscripts for publication in field-leading peer-reviewed journals (e.g., Magnetic Resonance in Medicine).
• Draft and submit abstracts to field-leading annual society meetings (e.g., ISMRM).

• Ph.D. in Medical Physics, Biomedical Engineering, Electrical Engineering, Computer Science, Neuroscience, or a related field.
• Experience with signal processing, data modelling, non-linear optimization, and MR physics.
• Strong programming skills in MATLAB, Python, R, C++, and/or similar.
• Experience working with MRS data is desirable, but not strictly necessary.
• Ability to work independently as well as in a collaborative research environment.

• Hands-on experience with acquiring and analyzing in-vivo MRS data.
• Knowledge in solving complex optimization problems.
• Knowledge of statistical analysis methods for biomedical research.
• Experience with reproducible research, open science practices, version control (OSF, Git, Docker, Jupyter, R Markdown etc.).
• Strong publication record in relevant fields such as MRI/MRS, NMR spectroscopy, clinical neuroimaging, etc.

Salary: $62,232 - $62,232 a year
