Get Access To All JobsJob Summary
A Postdoctoral Investigator (PDI) position is available in the Biology Department at the Woods Hole Oceanographic Institution (WHOI) to study environmental impacts on plankton food webs and trophic dynamics in the Northwest Atlantic ocean ecosystem. The successful candidate will join an interdisciplinary research program focused on understanding how physical oceanographic variability influences plankton communities and the transfer of energy to higher trophic levels, including forage fish, marine mammals, and endangered North Atlantic right whales. The projects integrate long-term observations, ocean observing systems, statistical analyses, and ecosystem modeling to improve understanding and prediction of ecosystem variability across seasonal to decadal time scales.
Responsibilities
The PDI will contribute to several ongoing projects examining multi-trophic ecosystem variability in the Northwest Atlantic Ocean. Responsibilities may include:
- Analysis and synthesis of long-term plankton and oceanographic datasets from observational programs and model outputs;
- Development of statistical and machine-learning approaches (e.g., GAMs, Random Forests, synchrony analyses);
- Investigation of plankton population dynamics and trophic transfer;
- Participation in coupled physical-biological modeling and connectivity analyses;
- Preparation of peer-reviewed publications and conference presentations;
- Contributing to proposal development and collaborative research initiatives involving federal agencies, regional research programs, and academic partners.
The position provides opportunities to work with a broad interdisciplinary network of collaborators involved in ecosystem observation and assessment, biological-physical interactions, and ecosystem forecasting across the Northwest Atlantic ecosystem.
Qualifications
Applicants should have:
- A Ph.D. in biological oceanography, marine ecology, oceanography, ecology, environmental science, or a related field;
- Experience working on plankton ecology and pelagic ecosystem dynamics (preferred);
- Strong quantitative and analytical skills, with preference for experience in coupled physical-biological modeling, statistical analyses, and/or machine-learning approaches; Experience working with ecological or oceanographic datasets is preferred;
- Proficiency in scientific programming and data analysis (e.g., R, Python, MATLAB);
- A demonstrated record of peer-reviewed scientific publication; and
- The ability to work effectively in interdisciplinary collaborative environments.
Appointment
This is a two-year position based in the Biology Department at Woods Hole Oceanographic Institution, with the expectation that the successful candidate will work on site. Continuation into the second year is contingent upon satisfactory performance and the availability of funding.
Review of applications will begin on July 15, 2026, and continue until the position is filled. The tentative start date is September 1, 2026.
Application Materials
Applicants should submit:
1) A cover letter describing research interests and relevant experience;
2) Curriculum vitae; and
3) Contact information for three references.
Interested candidates should contact Dr. Rubao Ji (rji@whoi.edu) for additional information. Applications should be submitted through the WHOI Careers website: https://careers.whoi.edu.
Additional Job Requirements
Salary Range: $68,381-$75,498
The salary range provided for this position reflects the expected minimum and maximum base pay for new hires. Actual compensation will be determined based on factors such as relevant skills, experience, and qualifications, as well as internal equity and market conditions. In addition to base salary, eligible employees also receive a comprehensive benefits package.
WHOI accepts applications on a rolling basis - applications will be reviewed as they are received, and we encourage you to submit your application as soon as possible to ensure full consideration. While we will continue to review applications until the position is filled, and early applicants may have an advantage in the selection process.

Get Access To All JobsTips for Finding TN Visa Sponsorship in Investigator
Document your investigative credentials clearly
TN visa officers look for a direct match between your degree field and the investigator role. A criminal justice, forensic science, or law degree strengthens your case. Gather transcripts, licenses, and any professional certifications before outreach begins.
Target employers with recent visa filing experience
Insurance carriers, federal contractors, and large compliance firms regularly sponsor work visas for investigators. Identify employers with recent visa filings to find companies experienced with sponsoring skilled professionals. For Canadians, the TN process involves presenting employer support documentation at the U.S. port of entry; for Mexicans, apply through a U.S. consulate with employer support letters.
Search TN-specific roles through Migrate Mate
Generic job boards rarely filter for TN visa eligibility. Use Migrate Mate to find investigator roles at employers with recent visa filings, saving you from applying to positions that may require H-1B visa or PERM instead.
Get your offer letter to name the TN category
The offer letter is your primary border document. Ask the employer to explicitly state that the role qualifies under the USMCA professional worker category and that you'll perform investigative duties requiring specialized knowledge. Vague letters cause delays at the port of entry.
Prepare for specialty occupation questions at the border
CBP officers may ask how your degree connects to the investigator duties in your offer. Prepare a one-page summary linking your academic background to the specific investigative functions, such as fraud analysis, insurance claims review, or regulatory compliance.
Understand Mexican nationals face a consular process
Mexican professionals cannot apply for TN status at the border like Canadians can. You'll submit your application at a U.S. consulate with supporting documents, which typically adds several weeks to the timeline. Build that window into your start date negotiation with the employer.
Investigator TN Visa: Frequently Asked Questions
Does an investigator role qualify for a TN visa?
Investigator roles can qualify under the USMCA professional worker category when the position requires specialized knowledge tied to a relevant degree, such as criminal justice, law, or forensic science. The job title alone does not determine eligibility; the actual duties and the degree-to-role connection are what CBP and consular officers evaluate.
How does TN visa sponsorship for investigator jobs compare to H-1B?
TN is faster and has no annual lottery, which makes it a practical alternative to H-1B for qualified Canadian and Mexican investigators. H-1B requires employer filing, a cap selection process, and months of waiting. TN-eligible Canadians can begin work almost immediately after a successful border application, while H-1B holders must wait for a designated start date.
Where can I find investigator jobs that offer TN visa sponsorship?
Most general job boards don't flag TN visa sponsorship explicitly. Migrate Mate is built for Canadian and Mexican professionals and filters for roles where employers have recent visa filings and experience with work visa sponsorship, so you're not spending time on positions that require a different visa pathway or won't support your status.
What documents does a Canadian investigator need at the border for TN status?
You'll need a valid Canadian passport, a detailed offer letter from the U.S. employer stating the investigator role and confirming TN eligibility, proof of your qualifying degree, and any professional licenses relevant to the position. CBP processes TN applications at the port of entry without a pre-filing requirement for Canadian citizens.
Can a Mexican national working as an investigator apply for TN status?
Yes, but Mexican nationals follow a consulate-based process rather than the border application available to Canadians. You apply at a U.S. consulate in Mexico with your offer letter, degree credentials, and supporting documentation. Processing timelines vary by consulate location, so coordinate your expected start date with your employer accordingly. Migrate Mate can help you identify employers familiar with this process.
