Academic interests

During my PhD I will be working with the Galactic and Extragalactic Astrophysics group led by Mark Dijkstra. We will be studying the radiation produced by stars and quasars and its interaction with galaxies and their surroundings at different epochs. We use analytical and numerical calculations as well as simulations for our purposes.


I did a master in Astrophysics, Particle physics and Cosmology in the University of Barcelona (2014).  Thesis title:  'The mean metal line spectrum of Damped Lyman Alpha systems in BOSS'. Supervisor: Jordi Miralda Escudé.
