He holds degrees in Chemistry (Univ. Ramon Llull,1994) and Chemical Engineering (IQS, 1995). After obtaining a Ph D in Organic Chemistry (University of Barcelona, 1999) he joined the group of Lewis Kay in Toronto for a post-doctoral stay (University of Toronto, 2000-2004). He was then recipient of a Ramon y Cajal reincorporation contract at the Parc Cientific de Barcelona (2004-2006) and he currently is group leader at the CIC bioGUNE. His research line focuses of the use of nuclear magnetic resonance (NMR) to the study of biologically relevant proteins and enzymes, paying special attention to the delicate balance existing between protein stability and dynamics. Such knowledge is applied for the development of new compounds with therapeutic activity, specifically in the field of rare diseases. He have published more than 55 papers with a total number of citations (1998-2015) of 2050 and an h-index of 17. He was the Spanish delegate for the trans domain of the COST program (2009-2014). He was awarded the prize of the Real Sociedad Española de Química (2004) and the Spanish NMR group prize (2005). He currently is the president of the Spanish NMR group.

Protein stability (thermodynamic and kinetic) drives the biophysical properties of the polypeptide chain (protein folding) and the protein's concentration in the cellular environment (protein homeostasis). It is the result of a delicate balance between inter- and intramolecular interactions, which can be easily altered by mutations and/or upon changes in the composition of the surrounding media. In this context, NMR spectroscopy offers a plethora of suitable experiments to investigate protein stability. In our laboratory we are currently interested in the following topics:
-
Pharmacological chaperones. Rare diseases (~7000 identified to date) are an area of significant medical need affecting an estimated 350 million people worldwide, with ~95% having no currently approved drug treatment. They are often produced by inherited mutations affecting the activity of a protein and It is becoming increasily clear that, most frequently, a mutation destabilizes the protein/enzyme, ultimately affecting its intracellular homeostasis. In this context, pharmacological chaperones (small molecules which bind to the protein, restoring stability and activity without affecting its function) can be applied to many diseases. In our laboratory we are investigating new methods (NMR, biophysical and biochemical) for the discovery and characterization of pharmacological chaperones against a set of diseases: congenital eryhtropoietic porphyria, tyrosianemia.
- Environmental modulation of enzyme stability. The high catalytic efficiency and the exquisite enantioselectivity of an enzyme has been employed in some industrial processes to upgrade their properties in order to make them more environmentally-friendly. However, large scale industrial implementation of biotechnological reactions is often limited by the marginal stability of the enzyme in the reactor conditions. In our laboratory we employ NMR and circular dichroism to investigate the effect of external crowding agents to improve the activity and stability of several enzymes. Specifically, we are investigating the mechanism for protein haloadaptation by a combined use of site directed mutagenesis and high-resolution NMR spectroscopy.
