Education

BSc in Chemistry (1992), University Complutense of Madrid (UCM). Spain.

MSc in Biophysics (1992), UCM.

PhD in Chemistry (1999), UCM.

Research Positions held

1992-1993 Ph.D. Student in the Biophysics Group at UCM.

As a graduate student, I received rigorous training in theoretical biophysics and structural biology. Starting from a solid training in mathematics, informatics and biophysics, I worked on prebiotic evolution models and neural networks research fields. The latter founded my BSc work.    

1994-1998 Ph.D. Student at the Centro de Investigaciones Biológicas (CIB) of the Spanish Research Council (CSIC).

My PhD work focused on shape and size determination of proteins in solution from its Small Angle X-ray Scattering profile (SAXS) using genetic algorithms. This pioneer development makes it possible to retrieve significantly more structural information from the scattering patterns than previously believed. My thesis advisors were professors J.M. Andreu CIB (CSIC) and F. Moran (UCM). During this period of time I also learned to effectively interact with experimentalists

2000-2003 Associate Researcher at The Scripps Research Institute. CA, USA.

My postdoctoral tenure at TSRI at W. Wriggers’ lab provided me the opportunity to broaden my technical experience in multi-resolution structure analysis towards the modeling of the large-scale macromolecular assemblies on the basis of low-resolution density data from electron microscopy.

2004-2007 Tenure track researcher position at CIB-CSIC.

I came back to Spain with the Ramón and Cajal tenure track program to establish my own research group to broadly work on the development and application of computational methodologies for structural biology. During this period, I secured several grants as principal investigator.

2007-2010 Research Staff Scientist at CIB-CSIC. Group Leader.

2010-present Research Staff Scientist at Institute of Physical Chemistry (IQFR-CSIC). Group Leader.

I currently have a group of four people including myself. Our multidisciplinary team is trying to ask and answer relevant questions in structure modeling, structure flexibility, protein interactions and drug discovery.

Interests

I am particularly attracted to the analysis and modeling of macromolecular machines whose actions and interactions are essential for cellular function. My research interests include new hybrid methods to combine multiresolution structural information of complementary biophysical techniques (X-ray, EM, SAXS etc.) and, new methods to analysis and predict the dynamical behavior of these complex systems using coarse-grained simulations (e.g Normal Mode Analysis). More recently, I also interested in computer-based methodologies to aid the structure rational design of new active compounds. These research lines are well supported by wide number of collaborations.
