Group Leader at EMBL-EBI. Our group uses interdisciplinary approaches including network analysis, omics integration and mathematical modelling to study the context specific regulation of human cell signalling.

New preprint alert! We integrated plasma proteomics, whole-blood transcriptomics, machine learning and network propagation to dissect high-risk thrombotic primary antiphospholipid syndrome (APS). 🩸🧬https://www.medrxiv.org/content/10.64898/2026.06.26.26356680v1

Grant writing tips from a grumpy reviewer ploughing through grants. 1. Often your reviewers are going to come from a broad range disciplines adjacent but *not actually in* in your field. Help us get orientated in the summary with an analogy/sketch and go back to analogy / sketch throughout.

Is #AI hitting a plateau in structure prediction? Help us find out at CASP17! 🧪🧬 Calling for Targets: Immune Complexes, protein - ligand complexes, RNA/DNA, conformational ensembles, membrane proteins, viral origins, and large complexes. The Rule of Thumb: If AF3 can’t model it, we want it.

The Critical Assessment of Structure Prediction (CASP) experiment is calling for prediction targets: Immune Complexes, Organic Ligand-Protein Complexes, Nucleic Acids and Complexes, Conformational Ensembles, Difficult Protein Structures and Complexes. 
Rule of Thumb: If AlphaFold3 can generate a high-quality model, it is likely not a CASP-grade challenge. If it struggles, we want it.

Our preprint is now published in MSB. link.springer.com/article/10.1... We decompose multi-omics into distinct phenotypic axes (drug response vs ARID1A-driven cell state), improving interpretation and revealing how baseline cell state rewires signaling and shapes MAPK inhibitor resistance.

Integrative multi-omics defines melanoma drug response networks and ARID1A-dependent resistance mechanisms - Molecular Systems Biology

Resistance to BRAF/MAPK inhibitors is a significant challenge in melanoma treatment, driven by adaptive and acquired mechanisms allowing tumor cells to evade therapy. We explored early signaling respo...

New preprint from our group @ebi.embl.org and the Vidal-Puig group! We combined pseudotemporal ordering of cross sectional MASLD patient data with network analysis to describe the disease progression and identify a signature of 24 plasma biomarkers for patient staging www.biorxiv.org/content/10.1...

EMBL is deeply saddened by the passing of our Interim Director General Peer Bork, a pioneering scientist who left an indelible imprint on life science research in Europe and beyond. We extend our deepest condolences to his family, friends, and colleagues. www.embl.org/news/people-...

On this day in 2021, I landed in a snowy, lockdown-silenced Heidelberg to start my lab. 5 years later we are a force to reckon with in our field, and the first generation are striking out on their own. I couldn’t be more proud, & grateful to them and our wonderful collaborators around the world 🌍 🧪

🧬 Kinase Inhibitors can do more than block their targets! A study by @cemm.oeaw.ac.at-@aithyra.bsky.social and #IRBBarcelona reveals that many inhibitors also trigger the degradation of the kinases, uncovering an overlooked mechanism with therapeutic potential. Out in @nature.com ➡️ bit.ly/43SD9xj
