To understand diverse microorganisms, their pathogenesis and resultant immune responses, research in MCB probes microbial physiology, the composition and function of microbiomes, innate and adaptive immunity, and translational strategies. This research and work helps us predict infection epidemics, design better therapies and reengineer host and microbe for improved health and industry.

Suggested Curriculum
The suggested curriculum outlined below is meant to guide you in choosing classes, they are not requirements. We highly encourage you to take the Foundational courses, while the Electives are more specialized and often cross between Areas of Interest. Remember to review the UW Time Schedule for the most accurate and up-to-date information regarding whether a course is currently being offered.
2025-2026 Suggested Curriculum (document download)
This track is broadly divided into the related sub-tracks of immunology, virology, and bacteriology. The foundational courses include two courses focused on each sub-track, denoted as:
1=Immunology
2=Virology
3=Bacteriology
Interested students can focus on one sub-track or mix and match from these sub-tracks depending on their specific area of research. Area directors or more senior MCB students can discuss these sub-tracks with interested students.
