Eric Cascales
CNRS Researcher.
After graduating in the laboratory of Roland Lloubès in 2002, I moved to Houston (Texas) for a wonderful stay in Pete Christie’s lab where I discovered the world of bacterial secretion systems. Back to Marseille, I launched the team on Type VI secretion. Although I love these nano-machines, I spend most of my time playing violin, listening opera, barocco violin and Glass’s Einstein on the beach, hiking to find wild orchids or kayaking or rowing in the calanques ! Who said I am monomaniac?
Laure Journet
CNRS Researcher. I performed my graduate studies in Aix-Marseille University in the group of Roland Lloubès (LISM, CNRS). My PhD thesis focused on the Tol/Pal proteins and colicin import. In 2001, I joined the laboratory of Guy Cornelis for a post-doc (in Brussels, then Basel) to study Type III secretion in Yersinia, focusing on the Type III needle length control. After six years in Strasbourg in Isabelle Schalk’s group, studying iron uptake in Pseudomonas aeruginosa, I came back to Marseille and bacterial secretion at the end of 2010 to join Eric’s group to study Type VI secretion. Besides the lab (in the “real life”) I like music, performing theater and not talking too much about myself !
Thierry Doan
CNRS Researcher.
Most of my scientific work has been dedicated to Bacillus subtilis. I used this model bacterium to study carbon metabolism during my PhD with Stéphane Aymerich and bacterial cell biology during my post-doc in David Rudner’s lab before I moved to Marseille in 2009 to work with Anne Galinier. That’s until 2017 when the god of secretion told me it was heresy and that 6 and 9 were the numbers at the origins of life. It was tremendously hard to leave B. subtilis behind, but I was very motivated by this new challenge and the scientific and technical exchanges with my new colleagues. From sheep embryogenesis during my undergraduate training to bacterial cell biology and secretion machineries, the common trait of my scientific work is my love for picturing small things. This is also true when I am out of the lab. When traveling, hiking, or simply playing with the kids, my camera is always nearby. More keywords about me can be found in this picture (gift from Jen, a friend in the Rudner lab).

Julie Viala
AMU Associate Professor.
I like to think of my career as a stroll that led me to visit different places, meet different people and work with a variety of microorganisms. I did my PhD at Pasteur Institute in Paris, where I worked on the soil bacterium Streptomyces in Philippe Mazodier’s group. In 2002, I went to Berkeley (USA) in Dan Portnoy‘s lab, where I studied the mechanisms regulating the toxicity of a pore-forming toxin of the facultative intracellular pathogen Listeria. I moved to Marseille in 2007. I first joined Frédéric Barras’ lab to work on stress adaptation of the facultative intracellular pathogen Salmonella, before being recruited as an assistant professor by Aix-Marseille University in Emmanuelle Bouveret‘s group. There, I investigated the links between lipid metabolism and the type 3 secretion system SPI 1 of Salmonella. Given our affinity for secretion systems, I joined the group of Eric in 2020 to work on bacterial toxins.
Regarding my hobbies, I like to walk and enjoy the magnificent landscapes that offer the Calanques for example, and I love to dance!
Maïalène Chabalier
CNRS Assistant Engineer.
After a superior technician diploma in Biochemistry in Marseille, I was hired at the CNRS in the group of Pierre Capy at Paris Sud / Saclay. There, I studied the mariner transposon in the fruit fly Drosophila. I then decided to return back to the sun and to change both the theme and model of my research. I joined the group of Sam Dukan at the Mediterranean Institute of Microbiology to study the impact of CO2 on the oxidative stress in Escherichia coli. I then moved for a short period in the group of Amel Latifi to develop a new biosensor. Finally, I joined the group of Eric to study the Type VI and IX secretion systems. I am afraid of not having much to say, but I always enjoy life !
Julia Bartoli
CNRS Engineer.
I first studied Chemistry in Montpellier for 5 years till 2007, and unfortunatelly after this time I think that I became allergic to organic chemistry and its complex chemical reactions, and I happened to be more and more interested by Biology and the Research field. I started to work during 3 years in Grenoble (IBS), developping carbohydrate microarrays to look for antiviral natural saccharides. This biochemistry experience was a good transition between my initial formation and the Biology road I wanted to follow. Then I worked for 2 years in the very interesting field of Giant Viruses in IGS laboratory in Marseille : a lot of cell culture and electron microscopy. After that, I finally got a permanent position as “Ingénieure d’Etude” at the CNRS, by joining in 2014 the LISM in the team of Emmanuelle Bouveret, where I worked on bacterial stress response mediated by “the magic spot” ppGpp. After Emma’s departure, I joined Eric’s team at the beginning of 2020, altogether with Dr Julie Viala with whom I closely work, and I now work on bacterial toxins ! Oh, I forgot : I come from Marseille and I am a half Corsican (which makes me very nice), I love travelling and I am a cat person!
Nicolas Rivard
Post-doctoral research associate
Long ago, bacteria lived together in harmony. Then, everything changed when the type VI secretion system attacked. Akin to a molecular crossbow, the T6SS translocates effectors from the cytoplasm toward a target cell. This formidable weapon allows an attacking bacterium to inject a range of toxins into innocent bystanders, often with nefarious consequences. Having dedicated my years of graduate studies to the transfer mechanisms of selfish mobile genetic elements and the intricate interplay between them, I myself can be described as the recent product of a transatlantic translocation event. After completing my PhD under the supervision of Prof. Vincent Burrus in my native Sherbrooke, Canada, I traveled across the pond to join Eric’s team in the winterless land of southern France. Together, we shall join forces to elucidate the evolutionary mysteries of interbacterial competition and save the world.

Maëlle Paillat
PhD fellow.
After a Bachelor degree of Biology in Angers, I left the “North” (as Marseille people say) for a Master in Microbiology at Aix-Marseille University. I discovered the Type IX secretion system during my first year of Master and immediately fell in love with this secretion machinery. So when Thierry offered me to join the team for the Master 2 internship, I couldn’t refuse. And then, I got a Ph.D fellowship to pursue my work on this fascinating machine ! When I’m not at the lab I like cooking, sewing, playing guitar and soccer.

Jonas Desjardins
PhD fellow.
I left Normandy to study microbiology in Marseille in 2016. During my iGEM internship in 2019, I spent most of my time in Éric’s lab to ask questions and in exchange, I brought some cakes. After that, I asked Éric for an internship in his team, and there started my journey studying type VI secretion system. I guess he said yes because of my (delicious) cakes. Then Eric suggested me to come back for the Master 2 internship, and it sounded like Mrs. Madrigal saying : “You are one of us now”. I immediately felt at home with this “logical family”. Otherwise, I love board games and reading when I am in the subway or in the gardens of The Longchamp Palace, my favorite author is Armistead Maupin.

Julius Martinkus
PhD fellow.
I got a master’s degree in molecular biology in 2021 at Vilnius University (yes, I came from Lithuania, a small European country by the Baltic Sea). During my graduate studies, I worked with the Type VI secretion systems, which fascinated me, so I decided to continue their research in the group of Eric. I can spend a lot of time in the lab because I lose my sense of time in it, so don’t be surprised if I say good morning in the evening. Apart from the lab, I like inline skating, fishing, reading books, snowboarding, wakeskating, and spending time with my friends.

Julien Giraud
PhD fellow.
After a small interlude in the medical field, I started studying biology in Marseille. I quickly discovered the fascinating research environment and joined Eric’s team for license degree internships. I rapidly felt in passion for secretion systems, and obviously for the Type VI secretion system. How do not fall in love with this surprising machinery? I couldn’t refuse to come back for my Master 2 internship and PhD to explore this fascinating system and work with this wonderful and welcoming team! Microbiology is not my only passion, I am also fond of classical art, old paintings, and French and Russian literature. I also love classical music, and to Eric’s despair, I am a fan of Rachmaninov.

Matteo Crespi
PhD fellow
I studied Biological Science and Technology and then Molecular and Industrial Biotechnology at the University of Insubria in Italy. During my internship at “The Protein Factory 2.0” lab, I worked on plastic-degrading enzymes. Later, I got a research fellowship to study enzymes that cause antibiotic resistance. While I was finishing my studies in Italy, I met Thierry and Elisabetta (my co-supervisor at the BIP 07 lab), who introduced me to the world of cell-penetrating peptides. After they went all out to get me to France, here I’m working on a research field that’s totally new and super exciting for me. Even though I love spending a lot of time at my bench, I make sure to set aside time for music (I’m also part of ‘team Rachmaninoff’), sports, traveling, and, being a regular Italian, good food.”
Yaëlle Aouizerate
PhD fellow.
After graduating in Chemistry and in Biology in Nice, I left the South to pursue my studies in Biotechnology in Lorient (Britany), where I discovered the rain. I also discovered the microbiology field, which immediately fascinated me. For that reason, I joined Eric’s team in Marseille for a Master internship on the gliding motility apparatus with Thierry, and was thrilling to get offered a PhD position ! Apart from the lab, I spend a lot of time fencing and sailing, and picking a new hobby every two weeks.
