I am excited to share that I will join the Friedrich Miescher Institute @fmiscience.bsky.social in Basel as a group leader, starting my lab in March 2026 🎉

We will explore cell fate regulation during organogenesis, with a focus on how cell elimination underlies the emergence of functional tissues.

If heterochromatin is really a liquid-like condensate, why is it not spherical?
We investigated whether mechanical interactions between a condensate and a fiber network can explain the variety of morphologies seen in phase-separated nuclear compartments

Excited to share the lab's 1rst preprint! Rapid high-res immunofluorescence is now possible in cultured & environmental diatoms thanks to 4-fold expansion microscopy. A step-change for comparative cell biology in one of the most important phytoplankton groups on the planet 🥳

Characterizing protein sequence determinants of nuclear condensates by high-throughput pooled imaging with CondenSeq Nature Methods - CondenSeq is an imaging-based, high-throughput platform for characterizing condensate formation within the nuclear environment, uncovering the protein sequence features that...

In the nucleus, many intrinsically disordered proteins (IDPs) form condensates. What IDP sequence features drive this behavior? We developed CondenSeq, a high-throughput approach to measure nuclear condensate formation, and applied it to ~14,000 IDPs to find out!

BREAKING: A federal judge reversed National Institutes of Health's terminations of hundreds of critical research grants that were canceled because of their alleged connection to disfavored topics, including diversity, equity, inclusion, and gender identity.

This is a major win for public health.

Happy Pride Month, humans! I invented the rainbow, but you made it beautiful!

Happy to share that I’ve (finally) started my PhD at UNSW Sydney. I’ll be investigating biomolecular condensates and am excited to connect with the Australian life sciences community !

I’m incredibly proud to share the results of our lab’s first project, leading to the exciting discovery – Aging promotes reactivation of the Barr body at distal chromosome regions – now published in @nataging.nature.com!

Blebbisomes are one bleb away from a functional cell Nature Reviews Molecular Cell Biology, Published online: 09 April 2025; doi:10.1038/s41580-025-00849-wThe authors of a new study characterize blebbisomes, large extracellular vesicles that contain functional mitochondria and other organelles and have significant roles in inter-cellular communication and the tumour microenvironment.

New Online! Blebbisomes are one bleb away from a functional cell

The reason biologists in your timeline are furious by this PR: the idea that species that diverged millions of years ago have only 20 genetic differences defies the fundamental principles of evolution. Like saying you turned a Honda Civic into a Formula 1 car by changing the oil

Happy to share the latest story from @arnaudkr.bsky.social's lab @embl.org! With @guidobarzaghi.bsky.social, we used Single Molecule Footprinting to quantify how often chromatin is accessible at enhancers after TF and chromatin environment changes!

Stem cell culture conditions affect in vitro differentiation potential and mouse gastruloid formation Aggregating low numbers of mouse embryonic stem cells (mESCs) and inducing Wnt signalling generates ‘gastruloids’, self-organising complex structures that display an anteroposterior organisation of ce...

Very happy to share that our paper on stem cell culture conditions is now out! doi.org/10.1371/jour... We found that modulating mESC culture conditions influences gastruloid elongation and lineage specification, and helps with making the protocol more reproducible in our hands! more below 🧵⬇️ [1/7]

How do so many students get to grad school without a reference manager? I am an unabashed @zotero.org zealot. Students are practically sobbing tears of joy when they find that there is a FREE tool that will organize and label PDFs, allow markup, and insert bibliographies!

HypoxyStat, a small-molecule form of hypoxia therapy that increases oxygen-hemoglobin affinity A small molecule that increases oxygen-hemoglobin affinity was shown to prevent and reverse pathology in a mouse model of mitochondrial disease, thereby enabling a practical form of hypoxia therapy.

OMG it's out! The latest from Gladstone Institute of Cardiovascular Research: Isha Jain's lab, with an outstanding discovery of a small molecule that can mimic hypoxia, to treat neurodegenerative diseases. The amazing Sylar Blume, an RA in Isha's lab, is first author! www.cell.com/cell/fulltex...

How a Canadian scientist and a venomous lizard helped pave the way for Ozempic - National | Globalnews.ca In 1984, Dr. Daniel Drucker, an endocrinologist from the University of Toronto, discovered a hormone that helped pave the way for popular diabetes drugs such as Ozempic.

This is the most relevant article to NIH and research cuts I’ve seen.

Imagine if this was today , how many people would be saying “Why are we studying Gila Monsters and their impact on diabetes ? That’s wasted money !”

Chromatin-based memory as a self-stabilizing influence on cell identity - Genome Biology Cell types are traditionally thought to be specified and stabilized by gene regulatory networks. Here, we explore how chromatin memory contributes to the specification and stabilization of cell states...

"Everything in epigenetics is circular". Here, we explore how memory that is stored locally on chromatin has a crucial role in stabilising cellular state, updating our view of the epigenetic landscape from one shaped by the genotype, to one moulded by experience
