Assistant Professor at @isbscience.org studying single-cell lifestyles of bacteria.

Proud to share our single-cell transcriptomics approach for the microbiome by instrument-free split-pool barcoding - metaSPLiT, developed by the incredible @monochamussutor.bsky.social together with @gibbological.bsky.social, @cdiener.com, et al. at @isbscience.org

🚀 Thrilled to share our first metaSPLiT preprint from @annabiosys.bsky.social's lab in collaboration with @gibbological.bsky.social! Explore hidden bacterial phenotypic heterogeneity in the human gut microbiome and discover the concept of "physiological guilds": www.biorxiv.org/content/10.6...

We sat down with Anika & Dmitry to discuss the new paper where we use bacterial scRNA-seq for studying bacterial phage infection and defenses. It turns out that bacteria use pre-existing variation in multiple layers of traits to protect themselves from unpredictable phages @isbscience.org

In the gut microbiome, bacteria are constantly under attack from viruses, but not all cells respond the same way. A new study uses single-cell sequencing to reveal hidden differences that determine whether bacteria survive or succumb to infection. isbscience.org/news/health/...

Pooled CRISPR screens with transcriptomics readout arrived for bacteria. We introduce mapSPLiT, an approach to profiling transcriptional responses to CRISPR perturbations at scale.

Pooled single-cell CRISPRa/i screens for functional genomics in bacteria at scale

Pooled CRISPR screens using single-cell RNA sequencing (scRNA-seq) have emerged as powerful tools to uncover gene function, map regulatory networks, and identify genetic interactions. However, the inh...

Estimation of diet from the metagenomics data is now possible! Curious to see how this can be applied for reanalyzing existing datasets to link the diet information with the data

Christian Diener@cdiener.com · last yr.

Happy to announce that MEDI, our method to quantify dietary intake through metagenomics is out now. 🧬 🧪🧫🦠 www.nature.com/articles/s42... #metagenomics #microbiome #microbiomesky So what is MEDI? A combination of two things:

What a stupid, petty move (rising to the top of the many many stupid, petty moves by this administration so far). Dispersing free HIV medication is one of the greatest unequivocally 'good' things the US does for the world. This program has saved 25 million lives. Why the fuck would you cut it?!

BREAKING: The Trump administration has instructed organizations in other countries to stop disbursing HIV medications purchased with U.S. aid, even if the drugs have already been obtained and are sitting in local clinics. www.nytimes.com/2025/01/27/h...

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service. “Pausing” grants means people don’t eat.

White House pauses all federal grants, sparking confusion

The Trump administration has put a hold on all federal financial grants and loans, affecting tens of billions of dollars in payments.

How can single-cell transcriptomics profile phage infection in individual microbial cells? Check out our preprint with Anika Gupta, Norma Morella, Dmitry Sutormin & other authors, in collaboration with Georg Seelig (UW) and Neel Dey (Fred Hutch). www.biorxiv.org/content/10.1...

Combinatorial phenotypic landscape enables bacterial resistance to phage infection

Success of phage therapies is limited by bacterial defenses against phages. While a large variety of anti-phage defense mechanisms has been characterized, how expression of these systems is distribute...

Finally caught up with some beautiful work from Alex Meeske in Nature! His lab has identified proteins in Listeria that either substitute for Cas in Cascade complexes (anti-type I-B CRISPR immunity) or degrade crRNA (anti-type VI-A CRISPR immunity). Inspiring stuff! www.nature.com/articles/s41...

Diverse viral cas genes antagonize CRISPR immunity - Nature

We demonstrate that phages have co-opted cas genes from CRISPR defence systems, which subsequently evolved anti-defence functions.
