Our new preprint is online!
A beautiful adventure led by Jeffrey Liang with collaborators from UdeM, Roscoff, and the Rocha lab at Institut Pasteur.

Pavithra (Postdoctoral fellow, since September 2025) completed her PhD at the School of Chemical and Biotechnology, SASTRA Deemed University (India). Using genomics, bioinformatics, and evolutionary modelling, she explored how genetic parasites emerge, persist, propagate, and accumulate within bacterial genomes, shaping host population dynamics.
In the Le Roux Lab, she now focuses on the eco-evolutionary dynamics of Vibrio–phage interactions, combining bioinformatics and AI approaches — and proudly operates the most beautiful computer in the lab 😉

Nice discussions on every project, refreshing walks, and breathtaking landscapes on the road to Rimouski — fall was definitely here.
We were joined by two special guests: Damien Piel (from Alexander Harms’ lab) and mini Jack, the newest (and tiniest) member of the team.

There’s a park, located in the heart of Montreal, dedicated to those who have died of HIV/AIDS in Quebec!

Do you know this park?

Here’s a hint: it’s in the Village district, near Beaudry station.

The Parc de l’Espoir (that’s what it’s called!) has been around since 1991. Nestled at the corner of rue Panet and rue Sainte-Catherine, this park is much more than just a green space in Montreal’s Village. It’s a place of remembrance and contemplation, created as a tribute to those affected by HIV/AIDS in Quebec. It symbolizes the hope of a world without stigma, of a more supportive and better-informed society. Commemoratives plaques recall the lives lost, but also the courage of the communities that fought for dignity and rights. In the calm of its benches and the shade of its trees, Parc de l’Espoir invites us to reflect, to be compassionate – and to never forget.

The park was officially inaugurated in 1994, as a result of a movement to appropriate the area by mobilizing citizens and activists. It was last redesigned in 2021, following a public consultation. Today, a commemorative plaque is still present, in addition to a large motif on the ground. This large red ribbon integrated into the street furniture was inspired by the work of Keith Haring (1958-1990), a gay artist and leading figure of “graffiti art” and “neo pop art” in the USA in the 90s. This is a reference to the period in which the park was created.

The flag and coat of arms of the city of Montreal include an indigenous symbol!

Can you guess which symbol it is? Here is the flag of Montreal:

Maybe you’ve already noticed, but since September 13, 2017, at the center of the flag of the city of Montreal is a white pine tree. This tree is an important symbol in Aboriginal culture: it represents peace, harmony and concord, whose roots extend so that peoples can find the path to peace and close the weapons of war once peace has been established.

This white pine icon was added in honor of the Mohawks still living around the island of Montreal, to underline their contribution to the creation of the city of Montreal. The white pine is placed in the center of the flag to represent the link with indigenous peoples.

and have team meeting with her

led by two talented PhD students, Baptiste Darracq and Eloi Littner. Always a pleasure to collaborate with Celine Loot, Eduardo Rocha, and Didier Mazel from the Pasteur Institute, Paris.

A piece of work passed like a baton between two lives — one in Roscoff, the other in Montréal — with the help of wonderful collaborators!

When grad students finally leave the lab…
