Excited to share our latest paper @natmethods.nature.com We present a high-throughput framework to map cellular interactions at ultra-high scale – broadly applicable from whole-organism immune response mapping to personalized therapy response prediction (1/4). www.nature.com/articles/s41...

🧠 Excited to share my main PhD project! We mapped the regulatory rules governing Glioblastoma plasticity using single-cell multi-omics and deep learning. This work is part of a two-paper series with @bayraktarlab.bsky.social @oliverstegle.bsky.social and @moritzmall.bsky.social, Preprint at end🧵👇

FootprintCharter: unsupervised detection and quantification of footprints in single molecule footprinting data
Single molecule footprinting profiles the heterogeneity of TF occupancy at cis-regulatory elements across cell populations at unprecedented resolution. The single molecule nature of the data in princi...

Having a stressful day? Lay back, crack a beer open and read about how chromatin accessibility responds to perturbations of TF binding at the single molecule level bit.ly/3XQMFxN. I'm incredibly thankful to my PhD mentors @arnaudkr.bsky.social and Judith Zaugg for these super productive years!!

Cumulative TF binding and H3K27 Acetylation drive enhancer activation frequency
In eukaryotes, transcription factors (TFs) must continuously compete with nucleosomes to access their binding sites, leading to cell-to-cell variability in chromatin accessibility at regulatory region...

Ever wondered what drives hematopoietic stem cell (HSC) heterogeneity? In this preprint, our collaborative team uncovered that differences in HSC reconstitution kinetics play a key role in shaping stem cell heterogeneity and lineage biases. doi.org/10.1101/2025... (1/2)

A kinetics-based model of hematopoiesis reveals extrinsic regulation of skewed lineage output from stem cells
Residing at the top of the hematopoietic hierarchy, long-term hematopoietic stem cells (HSCs) are capable of self-renewal and sustained blood cell regeneration. Over the past decades, single-cell and ...
