Chemical engineer by training, I did my PhD in applied mathematics at the BioProcess Engineering Group (CSIC) under the supervision of Antonio A. Alonso and Julio R. Banga. Since the beginning of my scientific career I was interested in understanding the complex dynamic behavior of biomolecular networks and its connection with relevant biological functions. During my postdoc at ETH (D-BSSE) with J Stelling, I became familiar with the open questions and challenges in systems and synthetic biology. Back at CSIC I started my work on the automated design of biocircuits for synthetic biology and on efficient methods for stochastic modeling and simulation of gene regulatory networks, helping to provide insight on cellular decisions under stochastic noise. One of my fundamental research aims is to understand the role of molecular noise in relevant cellular functions and exploit this knowledge for the advanced design, analysis and control of biosystems.
