The Crewe lab uses transgenic mouse lines, cell culture and biochemistry to understand extracellular vesicle (EV)-mediated signaling during homeostatic and pathologic metabolic regulation. Our work has uncovered the existence of an expansive EV-mediated signaling network within the adipose tissue proper, and from the adipose tissue to other organs. This mostly adipocyte-derived EV population consists of exosome-like vesicles that carry proteins, RNAs and lipid species that can modulate a variety of signaling pathways in recipient cells. The focus of the lab is to determine how the various cargo of adipocyte EVs signal within the adipose tissue and from the adipose tissue to distal organs to modulate metabolism in obesity.

Get Access To All JobsTips for Finding TN Visa Sponsorship as a Biology
Verify your degree meets TN standards
TN status requires a bachelor's degree or higher in biology or a directly related life science. A general science degree may not satisfy the requirement unless your transcript shows coursework specific to biological sciences.
Target employers with active research programs
Biotech firms, university research labs, pharmaceutical companies, and federal contractors hire biologists under TN regularly. Government-funded research institutions are especially accustomed to sponsoring international professionals through treaty-based visa categories.
Search TN-sponsored biology roles on Migrate Mate
Filter by biology job title and TN visa sponsorship on Migrate Mate to surface employers already familiar with the USMCA process, so you're not educating hiring managers from scratch during the interview stage.
Prepare a TN support letter before your border appointment
Canadian citizens present their TN documentation directly at a port of entry. Your employer's support letter must specify your biology duties, your degree field, and why the role qualifies under the USMCA professional schedule, not just your job title.
Distinguish your role from unlisted biological specialties
USMCA lists biologist as a qualifying category, but roles like ecologist or microbiologist must be framed clearly as biology practice. Work with your employer to document how your specific duties map to the defined TN occupation, not a related field.
Confirm your employer can document specialty occupation duties
For TN status, the position itself must require a biology degree, not merely prefer one. Ask the hiring manager to confirm the job description specifies degree-level biological expertise before you accept an offer, since vague postings create complications at adjudication.

Find Biology JobsBiology TN Visa: Frequently Asked Questions
Does a biology role qualify for TN visa status?
Yes, biologist is an enumerated occupation under the USMCA professional categories. Your role must require a bachelor's degree or higher in biology or a closely related life science, and your actual duties must involve biological research, analysis, or applied scientific work rather than general laboratory support or administrative functions.
How does TN compare to H-1B for biology professionals?
TN is generally faster and more predictable for biology roles. There is no annual lottery, no cap for Canadian citizens, and no waiting period tied to a fiscal year. H-1B requires employer sponsorship months in advance and selection through a random lottery. TN can be obtained at a Canadian port of entry in a single day if your documentation is complete.
What documents does a biology employer need to provide for TN sponsorship?
Your employer must supply a support letter on company letterhead that describes your biology duties in detail, confirms the position requires a degree in biology or a related life science, states your anticipated length of employment, and identifies you by name and citizenship. This letter accompanies your credential package at the port of entry or consulate appointment.
Where can I find biology jobs that offer TN visa sponsorship?
Migrate Mate lets you search biology positions filtered by TN visa sponsorship, so you can focus on employers who already understand the USMCA process. This saves time you would otherwise spend determining whether a given employer is willing and able to support a TN application before you apply.
Can Mexican citizens use TN status for biology roles the same way Canadians can?
Mexican citizens qualify for the same USMCA biology occupations but must apply through a U.S. consulate in Mexico rather than at a port of entry. The documentation requirements are identical, but the process involves scheduling a visa interview and waiting for consular processing rather than same-day adjudication at the border.
