The Genomics and Biomedicine research group  (GXB) at the University of Vigo, expanded in 2018 in order to reach the critical size necessary to become truly multidisciplinary and to confront with confidence new, ambitious challenges in biomedical and genomic research.

The GXB group is currently coordinated by Diana Valverde, and includes three additional senior PIs (Carmen Rodríguez, Carlos Canchaya, and David Posada) and three junior PIs (Miguel Arenas, Iria Fernández-Silva, and Marta Tojo), together with postdocs, graduate students, and technical staff.

Our group is part of the Center for Biomedical Research (CINBIO) at the University of Vigo, a Singular Research Center of the Galician Government.

Our research is currently funded by the University of Vigo, the Consellería de Cultura, Educación e Ordenación Universitaria of the Galician Government, the Ministerio de Industria, Economía y Competitividad of the Spanish Government, and the European Research Council.


The GXB group focuses on three main research areas:

1. Genomics applied to pathogens and diseases
2. Nanomaterials in biomedicine
3. Marine genomics

In the area of Genomics applied to pathogens and diseases,GXB researchers collaborate in different research basic and applied around the genetic basis of human diseases (Diana Valverde),  cancer genomics (Diana Valverde, David Posada, Miguel Arenas, Marta Tojo, Alberto Vicens), and viral genomics (Miguel Arenas, Marta Tojo), using tools from personalized medicine, epidemiology and evolution.

In the area of Nanomaterials in biomedicine, M Carmen Rodríguez-Argüelles lab worked on the obtention of new nanoparticles with potential therapeutical applications, in collaboration with the Posada lab.

In the area of Marine genomics,  GXB researchers collaborate in several projects aimed to understand speciation genomics in marine organisms (Iria Fernández-Silva), and structural genomics and phylogenomics in mollusks (Carlos Canchaya, David Posada).

We want to thank the Spanish Cancer Association (AECC) for awarding us a research grant to study the role of the microbiome (virus and bacteria) as non-invasive biomarkers for the detection of premalignant lesions and colorectal cancer. Anonymous people have donated this money; much gratitude and tons of responsibility.

New Ph.D. fellowships!

Congratulations to Pilar Gallego and Pablo Fonseca for their Xunta de Galicia Ph.D. fellowships! Pilar is already working on SARS-CoV-2 evolution in Galicia, and Pablo is about to start working –together with Monica Martinez at the IISGS– on genomic biomarkers for lung cancer immunotherapy.
