🔬 About SaezLab¶

We aim to understand how signaling networks are deregulated in disease and use this knowledge to develop new therapeutics. We work across cancer, autoimmune, and fibrotic diseases by integrating large-scale omics data with mechanistic knowledge using statistical and machine learning approaches.

We are based at EMBL-EBI, the Medical Faculty of Heidelberg University, and are part of the MMPU and ELLIS Heidelberg.
