Microorganism-Host-Environment Interactions (IMHE)
The IMHE program stands out among regional offerings by providing students with a research-based education in the field of general and environmental microbiology, covering both basic and applied aspects.
The IMHE master’s program aims to provide in-depth knowledge of microbial systems, covering both the study of microorganisms as individual cells, populations, and communities within their environment, and their interactions with hosts (humans, animals, plants) and vectors. The program examines interactions at the molecular, cellular, and microbial community levels, as well as the effect of biotic and abiotic factors on these interactions. It explores the role of microorganisms in the functioning of both natural and anthropogenic ecosystems. The practical and applied aspects of microbiology are also covered, particularly the applications of biomass and microbial diversity in the fields of agriculture, the environment, health, and biotechnology.
Combinations of course units (TU) allow for two distinct tracks: one focused on “Basic Research” (Track 1) and the other on “Research & Development” (Track 2). This program thus offers students the opportunity to pursue a variety of career goals, with a high placement rate for students entering PhD 40 to 50%) or securing professional opportunities in industry or laboratories immediately upon graduation. Students in Profile 2 have the opportunity to earn a dual degree by taking TU courses offered by the IAE de Montpellier (subject to application review). The program is open to apprenticeship students.
This program draws on the strong regional research community in the field of microbiology and benefits from the active involvement of researchers, faculty members, and industry professionals from this community based in Montpellier and throughout the Occitanie region.
The IMHE Master’s program is open to students who have completed a Bachelor’s degree in Life Sciences with a specialization in Microbiology. It is also designed to provide specialized training in microbiology for students in medicine, pharmacy, dentistry, veterinary school, or engineering schools specializing in biological sciences and agronomy (such as the Institut Agro).

IMHE Master's students are producing original scientific research!
The work of IMHE students, in collaboration with students in the Bioinformatics master’s program, supervised by their respective academic advisors as part of the project BILL, led to the publication of an article in a peer-reviewed international journal:link to the article Klafack S., Fiston-Lavier A.-S., (…), Master student consortium, Gosselin-Grenet A.-S., Avarre J.-C. (2019). Cyprinid Herpesvirus 3 Evolves in vitro through an Assemblage of Haplotypes that Alternatively become Dominant or Under-Represented. Viruses 11, 754.

Students present their findings at conferences (JFV, JOBIM, Montpellier Omics Days, MicrobiOccitanie 2019, Microbes 2022, JFV 2024) and regularly participate in public science outreach initiatives (Science Festival 2020 and2021; Mediterranean Night of Women Researchers 2025; MicrobioPic exhibition 2022; video production).
Master's Degree (Year 1) in IMHE
Back-to-school meeting: September 1, 2026.


The first year (M1) of the program forms the foundation of the curriculum, covering the fundamentals of general microbiology and microbial ecology; it includes laboratory sessions and a field trip. TU allow students to follow one of two tracks, though this choice is not set in stone (students may switch tracks each semester).
Project-based learning andeducational innovation are emphasized. Through the pooling of expertise with the Master’s program in Bioinformatics in the Faculty of Sciences and the establishment of the Bioinformatics Learning Lab (BILL)—the first innovative interdisciplinary learning lab— students are encouraged to take an active role in their education by managing a mini-research project from start to finish (from field sampling to DNA extraction, sequencing, and analysis of microbial sequences in the first year of the Master’s program) and by disseminating their results (publication, conference presentations, in the second year of the Master’s program). More info on BILL and photos here.

Research-based training is also available through a long-term internship in a laboratory or company (4 months), culminating in the writing of a thesis and an oral defense before a panel of experts.

Master's Degree in IMHE
The second year of the M2 program builds on the fundamental and applied knowledge and related skills introduced in the first year. Students interact with numerous researchers who come to present their research on topics such as the molecular mechanisms underlying interactions between microorganisms and hosts (using a wide variety of models), the role of microorganisms in ecosystems, and their utilization.
The M2 program focuses on developing scientific research skills. Students work with bibliographic resources (research, comprehension, critical analysis, and synthesis) and pedagogical communication methods, and complete a long-term internship (6 months) that includes writing a scientific report and presenting it.
During the program, several TU dedicated to career development, during which students work on their professional and personal goals.

Upon completion of the M2, students take entrance exams for doctoral programs, notablyDS , or may enter the workforce directly in public research laboratories or corporate R&D departments; these career paths are made possible by the specialization choices available in the M1/M2.
