I studied Biological Sciences at UAB, Barcelona, where I graduated in 1991 and obtained the PhD in 1996. I then moved to the lab of Wilfred van Gunsteren at ETH, Zurich, a main reference in the field of computational modelling and simulation of biomolecular systems. These were extraordinary years in which we performed seminal work on the simulation of polypeptide folding by molecular-dynamics methods. In 2002 I was appointed as ICREA Research Professor and returned with this position to the Institute of Biotechnology and Biomedicine (IBB) of UAB, starting a new group in Computational Biology. Today, we focus our efforts on the identification and development of new strategies to combat infections by multidrug-resistant bacteria, using a range of computational and experimental approaches. In 2005 I was appointed Adjunct Professor at UAB to combine my research activities as an ICREA Professor with teaching at the post-graduate level. Since January 2011 I serve as Director of IBB.
