GROUP DESCRIPTION
Understanding how genome evolution reshapes development is a central challenge in evolutionary biology. Our research focuses on how gene loss, genome reorganization, and gene regulatory network rewiring contribute to evolutionary innovation in chordates.
We use the tunicate Oikopleura dioica as a model system, a marine chordate with an extremely compact genome that has undergone extensive gene loss and genome scrambling. This organism provides a unique opportunity to study how developmental systems remain functional—and can even generate novel traits—despite radical genomic changes.
Our work has shown that gene loss is not merely a regressive process but can act as an adaptive evolutionary force, often coupled with gene duplication and regulatory innovation (“less, but more”). We investigate how the dismantling of major developmental pathways, such as retinoic acid, FGF, and Wnt signalling, reshapes gene regulatory networks and developmental processes.
More recently, we have expanded our research towards the study of genome architecture, particularly genome scrambling and its role in generating gene losses and adaptive genomic variation. In parallel, we explore how environmental stressors, including anthropogenic pollution or climate-driven ocean changes, impact development and gene expression in marine organisms.
By integrating EvoDevo, Genomics, and Ecological approaches, our goal is to understand how organisms adapt to both genomic and environmental perturbations.
GROUP OBJECTIVES
To understand how gene loss and genome reorganization reshape developmental gene regulatory networks and contribute to evolutionary innovation and environmental adaptation in marine animals, with special focus on chordates.

Senior postdoctoral researcher (ORCID: 0000-0003-0632-9838)
I’m interested in understanding the impact of gene loss on the evolution and development of the heart in chordates, and how the deconstruction of the cardiopharyngeal gene regulatory network might have promote adaptive innovations in the transition from the ascidian-like sessile lifestyle in ancestral tunicates, the free-swimming lifestyle of appendicularians.
The results of my PhD have been published in the cover of Nature: https://rdcu.be/cBvIC
After a Juan de la Cierva postdoctoral fellowship in IBE developing CRISPR technologies in Blattella germanica, I’m currently back Cañestro’s lab developing new techniques of knockdown and gene silencing. I’m currently co-supervising the PhD of Constantino Andrés.

Senior postdoctoral researcher (MSCA fellow) (ORCID: 0000-0002-9502-9310 )
Currently, I’m interested in understanding the evolution of genome architecture and the genetic response of the defensome of marine embryos to environmental challenges, and currently I’m using Oikopleura dioica to understand its genetic adaptation to biotoxins produced by diatoms. My research combine both computational analysis as well as wet lab work. I’m currently co-supervising the PhD of Biel Cassà.

Postdoctoral fellow (ORCID: 0000-0002-1446-5832 )
Currently, I’m studying the evolution of tail muscle and its relationship with the transition from a sessile ascidian-like ancestor into a fully free-living appendicularian.

My PhD project aims to investigate the impact of marine noise pollution on the development of embryos of marine organisms and to characterize the adaptive genetic response to environmental stress.

My PhD project focusses on the development of new methodologies to manipulate genetically Oikopleura dioica, including CRISPR, and to transfer the new approaches to other model systems such other invertebrates or mouse cell culture.

My PhD project focuses on understanding how massive genome scrambling affects the evolution of genome architecture, with special attention to the generation of gene losses.

My master project focusses on the analysis of cardiogenic factors discovered after DGE of RNAseq after Hand knockdown in O. dioica
