LINC fellows

About

We are seeking two undergraduate students and two postdocs to serve as LINC fellows for the year 2024-25. We invite applicants from institutions with limited research resources, regardless of geographic location. The applicants are expected to have a research mentor in their home institution, who will provide a letter of support for their application. During the LINC fellowship year, the LINC fellows are expected to remain in their current program/institution, and to be engaged in a research project that can benefit from remote access to the data and computational resources of the LINC project, and collaboration with the LINC investigative team. Remote fellows will be “embedded” within one of the LINC teams virtually for a year, and will travel to Boston for a 5-day visit. 

The fellows will attend regular LINC team virtual meetings, gain access to the cloud-based computational platform of the LINC project, and work on a project that makes use of LINC imaging data. Undergraduates will complete a senior thesis project, and postdocs will conduct a project related to their ongoing research. Depending on the academic background and research interests of each fellow, projects might have a neuroscience, computational, or engineering focus. Fellows will be embedded into the team that best fits their focus. We will support LINC fellows to publish their results and/or to participate in team publications as appropriate. We will further assist them with career planning and encourage them to build long-term collaborations and mentoring relationships with our team members.

We welcome the applicants’ own ideas for research topics, and we will further work with them to develop these topics. Examples of research projects include (but are not limited to):

• Studying the organization of specific fiber pathways in the brain
• Studying brain vasculature or other structures, in relation to fiber pathways
• Implementing and testing image registration, segmentation, or tractography algorithms
• Implementing and testing tools for cloud-based visualization, annotation, and proof-reading
• Developing annotated training datasets to train and benchmark machine-learning algorithms
• Developing engineering solutions to improve image analysis, e.g., designing holders that provide fiducial markers compatible with multiple imaging modalities and can aid image registration.

Research teams

Each LINC fellow will be embedded within one of our investigational teams:

• Circuits team: The circuits team is seeking fellows with a background in basic or clinical neuroscience or neuroanatomy. Postdoctoral applicants should be pursuing research in brain circuitry or network analysis; undergraduate applicants should be interested in gaining experience in this area. The LINC circuits team aims to define the pathways involved in deep-brain stimulation (DBS) of the subthalamic nucleus; annotate these pathways using anatomic tracing in non-human primates (NHPs), as well as novel microscopy and diffusion MRI tractography techniques in both NHP and human; and study the role of these pathways in DBS patient outcomes.
• Computational team: The computational team is seeking fellows with a background in biomedical or computer engineering or computer science. Postdoctoral applicants should be pursuing research in medical image analysis; undergraduate applicants should be interested in gaining experience in this area. The LINC computational team aims to develop pipelines for pre-processing of imaging data; registration across sections, modalities, and brains; segmentation of axons in microscopy images; multi-scale tractography; cross-validation of axon bundles between modalities; sharing and remote interaction with the data.
• MRI team: The MRI team is seeking fellows with a background in physics or engineering. Postdoctoral applicants should be pursuing research in MRI physics or engineering, biophysical modeling, or image reconstruction; undergraduate applicants should be interested in gaining experience in this area. The LINC MRI team aims to develop and deploy diffusion and structural MRI protocols for ex vivo imaging of NHP and human brains, and in vivo imaging of patients; implement MR image reconstruction algorithms to minimize artifacts; and develop methods for forward and inverse mapping between axonal microstructure and diffusion MRI signals.
• Optical microscopy team: The optical microscopy team is seeking fellows with a background in physics or engineering. Postdoctoral applicants should be pursuing advanced training in optical design, microscopy, instrument control, automated image acquisition, visualization and analysis; undergraduate applicants should be interested in gaining experience in this area. The LINC optical microscopy team aims to design, build, and test platforms for whole-hemisphere polarization-sensitive optical coherence tomography (PS-OCT) with multiple illumination angles, and for rapid, spectrally multiplexed 3D single-objective light-sheet microscopy (LSM); integrate PS-OCT with LSM for imaging of fluorescent tracers in NHPs; develop protocols for clearing, immunolabeling, and LSM of cut sections; collect PS-OCT/LSM data from NHP and human brains.
• X-ray microscopy team: The X-ray microscopy team is seeking fellows with a background in physics or engineering. Postdoctoral applicants should be pursuing research in X-ray image physics, X-ray sample preparation, phase-contrast imaging, or tomographic image reconstruction and analysis; undergraduate applicants should be interested in gaining experience in this area. The LINC X-ray microscopy team aims to test, optimize, and deploy protocols for hierarchical phase-contrast tomography (HiP-CT) in human brains; collect multi-scale HiP-CT data from intact brains; collect HiP-CT at even higher resolution in samples excised from the area of the subthalamic nucleus; perform osmium staining and micro-CT in the excised samples to validate the HiP-CT contrast.

Eligibility

Undergraduate students must be within two years of finishing their undergraduate degree when the program begins. Postdoctoral fellows must have completed at least one year of postdoctoral research before the program begins. Both undergraduates and postdocs must be affiliated with their current home institution for the duration of the program. We place an emphasis on recruiting candidates who enhance the diversity of the LINC research team, as defined by the BRAIN Initiative PEDP. This includes, for example, women, underrepresented minorities, and candidates whose home institution is minority-serving or located in a low- or middle-income country.

How to apply

The deadline to apply for the 2024-2025 academic year was September 6th, 2024. Applications are now closed, however you can look at the applicant and mentor forms for the past year below. Once applications open again, both forms will need to be submitted for an application to be considered complete.

• Application form: Must be completed by the applicant.
• Letter of support form: Must be completed by the research mentor from the applicant’s home institution.
