I completed a BSc in Biology at Universitat de Barcelona (2002) and went on to earn a Master in Biomedicine and a PhD in Biology (2009) under the supervision of Ricard Solé at the Complex Systems Lab (Universitat Pompeu Fabra, Institute of Evolutionary Biology CSIC-UPF). During my PhD thesis I worked on dynamical systems and complexity in biological systems (replicator nonlinear dynamics). Upon obtention of my PhD degree, I moved to Valencia where I took up a postdoc position at the Institute of Molecular and Cellular Plant Biology (Consejo Superior de Investigaciones Científicas-UPV), where I went on with my research on virus dynamics and evolution working with Santiago Elena. In 2011 I moved to San Francisco for a second postdoc at The David J. Gladstone Institutes (University of California San Francisco, UCSF), where I focused on the theoretical and computational study of HIV-1 dynamics. Then I moved again to the Complex Systems Lab were I completed a third postdoc (2012-2016) working on cancer evolution, theoretical ecology and systems and synthetic biology. 

In November 2016, I joined the Centre de Recerca Matemàtica (Bellaterra, Barcelona) as a visiting scientist at the Computational and Mathematical Biology group lead by Prof. Tomás Alarcón. In 2017 I started as a senior researcher at CRM receiving a postdoctoral grant from "la Caixa" foundation. I have recently obtained a "Ramon y Cajal" fellowship, also starting my own laboratory within the Computational and Mathematical Biology Group: the Nonlinear Dynamics and Evolution (NoDE) Laboratory (see the web​).

I am also adjunct professor at Universitat Pompeu Fabra, teaching at the subject Complexity Science at the Computational Biomedical Engineering Master

Interests

Research lines

I am working on applied mathematics and nonlinear dynamical systems in biology. My scientific research spans the fields of cancer dynamics and evolution, tumor heterogeneity and and its relation to drug response and adaptability, and fitness landscapes theory for tumor evolution and cell differentiation. I am also interested in RNA virus dynamics and evolution, in systems and synthetic biology, and in theoretical ecology and population dynamics and transitions.
