I obtained my PhD in 2011 at the University of Barcelona under the supervision of Josep Maria Paredes with a thesis entitled The keV-TeV connection in gamma-ray binaries. I then worked for two years in the group of Felix Aharonian at the Max-Planck-Instut für Kernphysik in Heidelberg with the support of a Beatriu de Pinós Fellowship (Marie Curie FP7-COFUND program). In 2013 I moved to the University of Leicester, where I am part of the HESS and CTA collaborations.

Research interests

My primary research goal is directed towards understanding the processes driving particle acceleration and non-thermal emission in galactic objects with relativistic outflows through a combination of theoretical modelling and X-ray, GeV, and TeV observations. My main focus has been on gamma-ray binaries, but I am also interested in non-thermal processes in pulsar wind nebulae and supernova remnants. In most of my endeavors, I try to bridge the gap between theory and observations, so that as much physical inference as possible can be obtained from multiwavelength observations of nonthermal radiation.
