The Weghorn Lab is located at the Centre for Genomic Regulation (CRG) in Barcelona, Spain. Our research focuses on analyzing evolving systems, particularly cancer tumors and the human population. We analyze sequencing and other biological datasets and develop mathematical and computational approaches to estimate selection. An important aspect of this effort is to investigate mutational processes and the heterogeneity of the mutation rate.

We are part of the Joint Program on Evolutionary Medical Genomics.

Recent lab news

July 2025 Congratulations to Maria for being awarded a Boehringer-Ingelheim Fellowship to support her PhD research on the evolution of cancer mutagenesis.
April 2025 Check out our fun collaboration with the Toledo Lab on the impact of systemic hypoxia on tumor evolution.
February 2025 Our study on a mutational hotspot at transcription start sites in the human germline is now available as a preprint.
Congratulations to Nicola on her successful thesis defense!
In this preprint, we provide a new perspective on mutational signatures in mismatch-repair-deficient cells.
January 2025 We welcome Javier and Nica to the lab.
December 2024 Another doctor in the lab. Congrats, Hossam!
November 2024 In a collaboration with the great people from the Berg Group, we found tumors characterized by volume growth.
Excited to share that we received support from the Neuroendocrine Tumor Research Foundation (NETRF) for work on rare tumor genomics.
