Really nice to see this out online! This was part of my research in Mahipal’s lab at IISc. It’s been incredibly interesting solving the Lsr 2 puzzle with him. The project progressed very smoothly in collaboration with Sandeep Choubey's lab at IMSc.

I am thrilled with the news that our ERC Synergy proposal GeneMotors was granted!!

This prestigious grant allows Leonid Mirny (MIT), Wendy Bickmore (Edinburgh), Benjamin Rowland (NKI) and me to study the DNA-looping SMC motors proteins that control our chromosomes in the next 6 years
📣 Meet the new ERC Synergy Grant awardees!

Sixty-six research teams have been selected for funding, bringing together 239 scientists. Congratulations to all!

Soon available in my group: 1 PhD position to investigate prokaryotic histones. See our recent work that highlights the existence and diversity of prokaryotic histones (e.g. Schwab et al., TIBS, 2025; Schwab et al., Nat Comm, 2024; Hu et al., Nucl Acids Res, 2024). Please DM for informal enquiries.

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️
Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

New preprint with @gfudenberg.bsky.social

We find the rate of cohesin loop extrusion in cells is set by NIPBL dosage and tunes many aspects of chromosome folding.

This provides a molecular basis for NIPBL haploinsufficiency in humans. 🧵👇

NIPBL dosage shapes genome folding by tuning the rate of cohesin loop extrusion
Cohesin loop extrusion is a major driver of chromosome folding, but how its dynamics are controlled to shape the genome remains elusive. Here we disentangle the contributions of the cohesin cofactors ...

We found a new asymmetry in the large-scale chromosome structure: sister chromatids are systematically shifted by hundreds of kb in the 5′→3′ direction of their inherited strands! The work was led by Flavia Corsi, in close collaboration with the Daniel Gerlich lab.

In an exemplary in vitro/in vivo study, 1st authors ‪@btanalikwu.bsky.social‬ & Alice Deshayes showed that dense linear protein arrays (e.g. telomeres) do stop loop-extruding SMCs!

Great collaboration with Marcand lab.

In this paper, we identify two amino acid motifs on CTCF that impede cohesin-mediated DNA loop extrusion - important as CTCF and cohesin are crucial to the structure and regulation of our chromosomes.
