Overview
The Microbiology and Immunology programme includes the study of bacteria, fungi, viruses, parasites as well as the immune system. Students can investigate the ecology, evolution and environments of microorganisms, the diseases they cause, the microbiome and its influence on the immune system and our health, immunity and disease. We are seeking solutions to the problem of antibiotic resistance; using microbial engineering in industrial processing and environmental remediation; determining how our immune system can best protect us against infection and cancer; using this information to design new immunotherapies and treatments for inflammation and auto-immune diseases. Our research spans population and systems biology and ecology, organism behavior and function, as well as cell interactions and molecular mechanisms. Our graduates are extensively trained in analytical thinking, creative innovation, and effective communication. Degrees in our programme accelerate students in a wide variety of careers in industry, academia, not-for-profit organisations, and the business world.
What makes the program unique?
Microbiology has been an integral part of UBC since the university's inception in 1915. Our programme is a strong and collaborative community of microbiologists, immunologists, biochemists and cell biologists, based at UBC and affiliated hospitals. We promote fundamental and translational research and we enjoy strong connections to clinicians, engineers, and epidemiologists across Canada. Many of our students are located in the Life Sciences Institute, a world-class collection of scientists with core facilities for advanced flow cytometry, microscopy and imaging, and high-throughput biology together with the Facility for Infectious Disease and Epidemic Research. Other researchers are located in the Michael Smith Laboratories. We also work closely with a variety of local organizations such as adMare Bioinnovations and the Genome Sciences Centre, with opportunities for commercialisation and entrepreneurship.

Financial Support
Applicants to UBC have access to a variety of funding options, including merit-based (i.e. based on your academic performance) and need-based (i.e. based on your financial situation) opportunities.
Program Funding Packages
All full-time PhD students in the Department of Microbiology and Immunology will be provided with a funding package of $29,270 stipend plus a life supplement equivalent to tuition for up to five years of their PhD. The funding package may consist of any combination of internal or external awards, teaching-related work, research assistantships, and graduate academic assistantships.
Funding Statistics
Based on the criteria outlined below, 47 students within this program were included in this study because they received funding through UBC in the form of teaching, research, academic assistantships or internal or external awards with a mean of $43,833 and a median of $44,169.
This results in a net balance (any funding provided to the student minus tuition and fees) mean of $35,747 and median of $34,977.
- 23 students received Teaching Assistantships. Median TA funding based on 23 students was $7,205.
- 44 students received Research Assistantships. Median RA funding based on 44 students was $14,070.
- 5 students received Academic Assistantships. Median AA funding based on 5 students was $3,603.
- 47 students received internal awards. Median internal award funding based on 47 students was $10,569.
- 14 students received external awards. Median external award funding based on 14 students was $22,167.
Study Period: Sep 2023 to Aug 2024 - funding for full-time PhD students enrolled in three terms per academic year in this program across years 1-4, the period covered by UBC's Minimum Funding Guarantee. Mean and median values might mask variability in sources and amounts of funding received by individual students. Beyond year 4, funding packages become even more individualized.

Scholarships & awards (merit-based funding)
All applicants are encouraged to review the awards listing to identify potential opportunities to fund their graduate education. The database lists merit-based scholarships and awards and allows for filtering by various criteria, such as domestic vs. international or degree level.
Graduate Research Assistantships (GRA)
Many professors are able to provide Research Assistantships (GRA) from their research grants to support full-time graduate students studying under their supervision. The duties constitute part of the student's graduate degree requirements. A Graduate Research Assistantship is considered a form of fellowship for a period of graduate study and is therefore not covered by a collective agreement. Stipends vary widely, and are dependent on the field of study and the type of research grant from which the assistantship is being funded.
Graduate Teaching Assistantships (GTA)
Graduate programs may have Teaching Assistantships available for registered full-time graduate students. Full teaching assistantships involve 12 hours work per week in preparation, lecturing, or laboratory instruction although many graduate programs offer partial TA appointments at less than 12 hours per week. Teaching assistantship rates are set by collective bargaining between the University and the Teaching Assistants' Union.
Graduate Academic Assistantships (GAA)
Academic Assistantships are employment opportunities to perform work that is relevant to the university or to an individual faculty member, but not to support the student’s graduate research and thesis. Wages are considered regular earnings and when paid monthly, include vacation pay.
Financial aid (need-based funding)
Canadian and US applicants may qualify for governmental loans to finance their studies. Please review eligibility and types of loans.
All students may be able to access private sector or bank loans.
Foreign government scholarships
Many foreign governments provide support to their citizens in pursuing education abroad. International applicants should check the various governmental resources in their home country, such as the Department of Education, for available scholarships.
Working while studying
The possibility to pursue work to supplement income may depend on the demands the program has on students. It should be carefully weighed if work leads to prolonged program durations or whether work placements can be meaningfully embedded into a program.
International students enrolled as full-time students with a valid study permit can work on campus for unlimited hours and work off-campus for no more than 24 hours a week during academic sessions.
A good starting point to explore student jobs is the UBC Work Learn program or a Co-Op placement.
Tax credits and RRSP withdrawals
Students with taxable income in Canada may be able to claim federal or provincial tax credits.
Canadian residents with RRSP accounts may be able to use the Lifelong Learning Plan (LLP) which allows students to withdraw amounts from their registered retirement savings plan (RRSPs) to finance full-time training or education for themselves or their partner.
Please review Filing taxes in Canada on the student services website for more information.
Cost Estimator
Applicants have access to the cost estimator to develop a financial plan that takes into account various income sources and expenses.
Career Outcomes
75 students graduated between 2005 and 2013: 1 graduate is seeking employment; 1 is in a non-salaried situation; for 7 we have no data (based on research conducted between Feb-May 2016). For the remaining 66 graduates:
RI (Research-Intensive) Faculty: typically tenure-track faculty positions (equivalent of the North American Assistant Professor, Associate Professor, and Professor positions) in PhD-granting institutions
TI (Teaching-Intensive) Faculty: typically full-time faculty positions in colleges or in institutions not granting PhDs, and teaching faculty at PhD-granting institutions
Term Faculty: faculty in term appointments (e.g. sessional lecturers, visiting assistant professors, etc.)

| Year | Citation |
|---|---|
| 2024 | Dr. Hardman studied immunity to intestinal viruses. By contrasting related viral strains, subtle factors could be characterized which balance immunity between controlling infection and limiting inflammation. This work contributes to future vaccine efforts, and treatments for inflammatory disorders. |
| 2024 | Dr. Allanach focused on determining how viral infection influences autoimmune disease in a newly developed humanized mouse model of multiple sclerosis.She observed that Epstein-Barr virus worsened disease by altering the balance of beneficial and detrimental immune subsets in the brain. These findings have implications for how infections should be targeted in diseases like MS. |
| 2024 | Dr. Song explored how plants communicate with the microbial community surrounding their roots, known as the rhizosphere microbiome. She identified novel genetic mechanisms plants employ to interact with beneficial microbes. Her findings will help enhance crop resilience and productivity, offering important advancements in agricultural practices. |
| 2024 | Dr. Krekhno investigated the breakdown of steroids by mycobacterial pathogens and identified several genes that result in toxicity upon disruption. These insights into steroid utilization provide valuable information on how these bacteria cause infection and may contribute to the development of new, more effective therapies. |
| 2024 | Dr. Gauthier's thesis work outlined the development, optimized, and diagnostic test performance of pathogen-agnostic sequencing for diagnosis of respiratory viral infections. His thesis work helped to overcome key translational barriers to aid in the translation of genomic sequencing technologies for applications in diagnostic virology. |
| 2023 | Dr. Huggins studied how microorganisms use nitrogen in low-oxygen marine waters. She found that, in some cases, nitrogen can be recycled faster than it is lost from the environment. Her work adds to our knowledge about the impacts of oxygen loss and climate change in the oceans. |
| 2023 | Dr. Dostert studied communities of the highly antibiotic resistant bacterium Pseudomonas aeruginosa. She identified genes mediating community growth in diverse environments. Her research demonstrated the strong influence of the growth environment on the entire gene network and provided interesting gene candidates for the design of novel drugs. |
| 2023 | Dr. Morales Duran found that acidic environmental pH decreased the activity of antibiotics against the CF pathogen B. cenocepacia, and induced changes in the bacterium that are associated with host colonization and pathogenicity. |
| 2023 | Dr. Krekhno investigated mechanisms of pathogenic E. coli-caused infantile diarrhea, providing insights into host-microbe interactions. He employed computational and molecular biology tools to provide the first comprehensive overview of the changes in the regulation of gene expression during infection. |
| 2023 | Dr. Liu explored how plant-associated bacteria influence plant immunity and shield plants from pathogens. She discovered that bacteria dampen immunity through root acidification and protect plants via biofilm formation. Her work advances our grasp of plant-microbe interactions, offering insights into agricultural microbiome engineering. |
