It’s been really fun editing and giving feedback to people applying for the HHMI Gilliam Fellowship, and I think part of the reason is that it’s becoming increasingly clear what the next generation of scientists wants, what they value, and what they believe science can be

Reading these applications has made me incredibly optimistic about the future of science I know ECRs don’t have all the answers, but a lot of us are thinking about the BS that academia desperately needs to confront

It feels like every trainee in academia today is either actively (re)shaping, preparing to inherit, or has already decided to leave a system that doesn’t always reflect the values they hold

We spend so much time talking about “the future” of scientific discovery, but why not the future of the people responsible for making those discoveries What does it mean to “accelerate innovation” if we aren’t equally committed to expanding opportunity?

We’re living through a WACK time in science. Discovery and innovation are buzzwords, new technologies come out everyday, and talent is everywhere (BUT ofc opportunity is not)

I’ve only read 15+ applications so far and the science is dope, but the non-science is so impressive! Trainees deeply care about mentorship, community, accessibility, and creating environments where people can actually thrive… They want to do great science AND change how science is done

In February 2026, we captured this photo of Dr. JP Flores from the Scientist Network for Advancing Policy (SNAP) as he ran across the plenary stage at the 2026 annual meeting of the American Association for the Advancement of Science (AAAS) in Phoenix, Arizona.

How does gene expression change during regeneration? Are specific enhancers activated or is there extensive genome re-modelling? Working with the team of Guillermo Orsi, we show that insect (cricket) and crustacean (Parhyale) genomes become re-modelled on a genome-wide scale.

Have you ever looked at a gene in IGV or a genome browser and wondered “What are all those (ATAC-seq/H3K27ac/CTCF ChIP-seq/…) peaks doing?” 🤔 I’m thrilled to share that we developed a new technology called Swap-seq to answer that exact question. Swap-seq: www.biorxiv.org/content/10.6...

We are excited to share research, but I want to take some time to share a little about myself. I LOVE science, but I also spend a lot of time advocating for more inclusive science. This work is promoted by my own obstacles in pursuing science which I talk about here: www.cell.com/cell/fulltex...

1\ We know a bit about how 3D chromatin interactions are formed, but what do we know about how they are disrupted? We asked this question in our latest preprint: doi.org/10.64898/202..., focusing on the massive loss of promoter interactions during neuronal differentiation.

doi.orgDevelopmentally programmed loss of long-range Polycomb interactions is regulated by cohesinDistal regulatory elements (DREs), such as enhancers, can regulate genes across megabase-long distances, presumably via coming into close spatial proximity. The establishment of new transcriptional programmes during cell type transitions is associated with widespread rewiring of the spatial organisation of the genome, including gain and loss of chromatin interactions. Extensive effort has been invested into understanding how chromatin interactions are formed during development, yet the mechanisms underlying their developmental loss remain largely unclear. By leveraging chromatin accessibility-assisted footprinting, acute protein degradation and chromatin conformation capture, we show that loss of promoter interactions cannot be explained by reduced binding of sequence-specific transcription factors (TFs). Instead, we identify a subset of interactions that depend on cohesin for programmed developmental disruption. These sites are characterized by high Polycomb enrichment and TF occupancy and engage in strong long-range interactions that undergo extensive differentiation-dependent rewiring. Preventing interaction loss by acute cohesin degradation results in the preferential downregulation of associated genes. Together, these results suggest that cohesin indirectly regulates developmental loss of Polycomb interactions by enabling the acquisition of other potentially regulatory contacts in a process that may shape transcriptional programs during cell type transitions. ### Competing Interest Statement The authors have declared no competing interest.
