Assistant Professor at the University of British Columbia studying the gut microbiota and abiotic environment in health and disease.

Dear microbiology twitter, what are tricks, assumptions and inside knowledge microbiologists have when culturing bacteria that aren't obvious to non-microbiologists? E.g. motion of air being a source of contamination, not touching the rim of threaded tubes etc.

CIHR funding rate: 13.6%.
Early 2000s: 30%+.

Canada’s new $1.7B Impact+ program recruits talent — but without increased Tri-Council base funding, we risk further strain on an already stretched system.

We’re calling for $1B over 5 years.

Excited to share our latest publication, led by Dr. Ellie McCallum and Juan Burckhardt!

[UBC Dept of Microbiology and Immunology @UBCMicroImmuno]

UBC researchers have engineered gut bacteria that dim their fluorescent glow in the presence of illness.

Their findings, published in Cell, could improve gut diagnostics by using bacteria that already live there.

A new UBC study could help guide strategies to make colonoscopies safer for people with inflammatory bowel disease, who undergo the procedure more frequently than the general population. @UBCMicroImmuno @CTropini

Sculptor: the missing UI for Claude Code 🎨

Imagine running 5 Claudes in parallel, safely in containers, while you stay in flow. Then bring their work straight into your IDE to test/edit together.

This is how one developer ships like a team. Try it with Sonnet 4.5!

CIFAR’s Diet Module, developed by @CTropini, equips educators to think more holistically about how our dietary choices shape the microbiome and influence health outcomes.

[CIFAR @CIFAR_News]

Introducing CIFAR’s new Public Health Microbiome curriculum!

Led by experts @MeghanAzad, @CTropini, @Naama_GZ and Melissa Melby, it bridges cutting-edge microbiome science with real-world public health practice.

Congratulations to Brian on an awesome 3 minute presentation!!

[UBC Dept of Microbiology and Immunology @UBCMicroImmuno]

Last week, MBIM undergraduate students participated in UBC’s first Life Sciences Undergraduate 3-Minute Thesis competition. MBIM student Brian Deng from the Tropini lab (left) was awarded first place for a succinct and compelling narrative on his research. Congratulations to all!

Really excited to share new exciting work led by PhD students McCallum and Burckhardt! We created a new series of syn bio tools in Bacteroides to create non-invasive, real time and sensitive in vivo gut biosensors.

Expanding the Bacteroides synthetic biology toolkit to develop an in vivo intestinal malabsorption biosensor. https://t.co/f0Oy9ijFZe #biorxiv_synbio

Excited to share our preprint led by Dr. Hunter! We show that osmotic shifts, common in the gut due to diet & laxatives, alter T4 phage-E. coli evolution. High osmolality promotes fitness but selects for mucoid, weakly phage-resistant E. coli, with implications for phage therapy!

Osmotic conditions shape fitness gains and resistance mechanisms during E. coli and T4 phage co-evolution https://t.co/rgzff9wiEE #biorxiv_micrbio

@AnnaBlakney That's awesome, congrats Anna!!

[Carolina Tropini, PhD @CTropini]

@AnnaBlakney So cool!! Thanks for sharing. Have you seen Ron’s book (and website) with Rob Phillips, Cell Biology By the Numbers? https://t.co/vrfetjhl8T
It’s more of this, and really great.

[Annie Vogel Ciernia @AVogelCiernia]

Excited for our new work to be officially published https://t.co/jZDGhcD2pd! This study in collaboration with @CTropini 's group reveals that early-life gut inflammation leads to sex-dependent changes in the microbiome-endocrine-brain axis.

[Carolina Tropini, PhD @CTropini]

Very excited to share a new paper in collaboration with @AVogelCiernia! We show that early-life inflammation alters sex hormones and mating behavior in mice, alongside shifts in hormone-modifying microbiota members! Great work by Olivia, Claire and others! https://t.co/QebwAgXDIE
