Molecular Microbiology Curriculum
The PhD in Molecular Microbiology at Tufts University Graduate School of Biomedical Sciences (GSBS) combines rigorous academic instruction with hands-on research training in microbial pathogenesis, genetics, and host–microbe interactions. Students complete core coursework, lab rotations, and seminars in their first two years, transitioning to full-time dissertation research after selecting a thesis lab.
First-Year Overview
In your first year, you’ll complete:
- Didactic courses in microbiology, biochemistry, and scientific ethics
- Three research rotations across Tufts’ 21 active labs
- Seminars and journal clubs that sharpen critical thinking and presentation skills
In the early Spring of Year 1, students select a thesis advisor and begin full-time dissertation research, which continues until an appropriate body of work has been assembled.
Didactic Coursework
All MMB students complete foundational courses in microbiology and biochemistry, as well as required training in research ethics. Students in the MERGE-ID and Molecular Genetics tracks follow specialized curricula aligned with their focus areas.

Qualifying Exam
By the end of the second year, students complete a written and oral Qualifying Examination. Working with a faculty committee, students prepare a written research proposal distinct from their thesis topic, then defend it in an oral exam. The Qualifying Exam is typically completed within 12 months after course work begins for all students. This process builds independent thinking, experimental design, and scientific communication skills.
Seminars & Guest Speakers
Students attend weekly seminars featuring leading scientists in microbiology, immunology, and genetics. The series is shared with the Immunology and GMCB Graduate Programs. These sessions foster interdisciplinary learning and provide opportunities to network with invited speakers. Most seminars are take place on Wednesdays at noon and are followed by a catered lunch for select students with the speaker.

Research Presentations
Students present their research to the whole program annually. Students do so beginning in their second year and present once every year until their thesis defense. We view learning to create and deliver professional quality presentations as an important part of the training experience.
Faculty members and other senior researchers help students organize their data, create clear and informative slides, and present their work in an interesting and compelling manner.
Research Reports are traditionally held on Tuesdays at noon. All students are required to attend all research reports throughout their time in the program.
Research Presentations
Starting in the second year, students present their research annually to the MMB community until their thesis defense. These workshops offer a platform to receive feedback, improve public speaking, and prepare for eventual thesis defense. Presentations are often paired with thesis advisory committee meetings for real-time input from mentors.
Journal Club
The MMB Journal Club helps students develop the skills to critically evaluate scientific literature and lead informed discussions. Held monthly in small-group settings, the club is required for:
- PhD students: 4 years
- MD/PhD students: 3 years
Attendance is required, and participation builds the analytical foundation essential for research success.
