Our work on chromatin evolution in brown algae is finally out! This is also my first "co-first author" paper!! I’m excited to share what we found 👇

Heya science peeps, my first first-author paper is on Biorxiv! We show how transcriptome-wide expression variability in outbred animals responds massively to an environmental stressor and is underpinned by cryptic variability- (not just mean-) controlling alleles. www.biorxiv.org/content/10.6...

New CRISPR tools for brown algae: a transgene-free genome editing methodology, developed in Ectocarpus and validated in kelps such as Undaria pinnatifida, opens new possibilities for functional genomics, aquaculture, and blue biotechnology. Online ahead of print: doi.org/10.1016/j.cr...

Looking back at a highlight from 2025: Great energy at the 2025 SALTO Symposium we organized at the MPI for Marine Microbiology! Researchers from Germany, France, Spain, Portugal, and Australia joined us in Bremen to explore the evolutionary links between specialized bacteria and their algal hosts.
