Resistance to antifungal medications is growing. Now, #UofG researchers have developed a faster way to identify the genetic vulnerabilities of Candida fungi, which could lead to brand new treatments. @uofgcbs.bsky.social @uofgresearch.bsky.social uoguel.ph/vze5i

Faster Gene Screening Method Targets Deadly Fungus
U of G researchers are using CRISPR interference to spot genetic vulnerabilities in Candida albicans, a leading cause of life-threatening infections.

📣 New preprint on @biorxivpreprint.bsky.social: Bacteria rewire fungal antimicrobial gene expression in microbial arms races www.biorxiv.org/cgi/content/... This work, led by outstanding @jinyi-zhu.bsky.social, shows that bacteria suppress fungal antimicrobial protein expression to evade antagonism

Pooled CRISPRi screening reveals fungal-specific drug target candidates
Nature Microbiology, Published online: 11 May 2026; doi:10.1038/s41564-026-02356-wThis study presents a pooled CRISPRi screening approach in Candida albicans to investigate essential genes at scale, revealing environment- and strain-dependent gene sensitivities and conserved vulnerabilities relevant to antifungal drug discovery.

This work was led by one of the very first *superstar* undergrads to set foot in my lab (Lauren), whom I was fortunate to convince to stay on and complete it as a PhD student. She was joined by computational wizard postdoc @pdespres.bsky.social, and together they grew this into quite a cool story.

In this work, we focus on essential genes as putative antifungal drug targets, but I think (and hope!) there are many cool ways others can use these tools to probe important questions in fungal genetics. We have a few of our own ideas too ;)

One thing I think is particularly exciting is the portability of the system for systematic comparative analysis of gene function. So we can make and compare large libraries of genetic mutants on a high-throughput scale, across diverse strains, clinical isolates, etc.

We use this technique to target and study essential genes in C. albicans. Using the power of CRISPRi to identify genes that are highly dosage sensitive, and ones that are conserved in their essential function across diverse environmental conditions and genetic contexts

In this paper, we developed a regulatable pooled CRISPRi platform for high-throughput, scalable (and portable!) gene repression screening in the fungal pathogen Candida albicans

It's been a long time coming to finally see this in print! While not the first paper from my lab, it is one of the very first projects we started working on from day 1 links.springernature.com/f/a/1IP7gCfA...

And, a real missed opportunity to call them "6ixis"

see you on the other side! remember that here they call Bixis 'Bike Share Toronto'. An excellent example of Toronto adopting fun things from Montreal and making them less cool.

It's Mycology Monday! 🍄 Which reminds me! CanFunNet registration is now open: canfunnet.conferences.uwo.ca/registration If you study fungi, this broad fungal conference is a great one to attend (or present at).

Antifungal resistance isn’t just about one gene.🧬 Researchers led by PhD student Nick Gervais & @shapirorebecca.bsky.social have developed a new CRISPR tool that can control multiple genes at once in fungal pathogens. SCRIBE🗞️: www.uoguelph.ca/cbs/news/202... @uofgresearch.bsky.social

PIs/group leaders, what was the most important aspect of the first paper your lab published 1️⃣ Establishing the lab's identity 2️⃣ Communicating an important discovery 3️⃣ Completing a project started as a postdoc 4️⃣ Other 📊 Show results
