I am a Postdoctoral Research Associate at the Department of Physics and Astronomy and the Pittsburgh Particle Physics, Astrophysics, and Cosmology Center (PITT PACC) of the University of Pittsburgh.
I received my PhD in Physics from Universitat Autònoma de Barcelona (UAB) in 2011 under the supervision of Dr. Ramon Miquel. After two years as a post-doctoral researcher at the Centro de Astrofísica (CENTRA), I was a Fondecyt fellow working with Prof. Mario Hamuy at the Departamento de Astronomía (DAS) of Universidad de Chile (UC).
The topics of my research are concerned with supernova physics and observational cosmology. I have worked in characterizing the environment of supernova explosions, and how such properties can provide clues on both the characteristics of the progenitor stars and the physics of the explosions. I also developed a new pure photometric technique to convert type IIP SNe into useful cosmological standard candles. Currently, I am working in improving the standardization of type Ia SNe through the study of their local environment.
I was born in Granollers, Barcelona, so my first and last names are Catalan: LL is a digraf that is pronounced as a palatal lateral approximant /ʎ/ (such as papillon in French, bacalhau in Portuguese, or tagliatelle in Italian), Í should be written with a diacritic because my first name is disyllable and has the strength at the end, and NY is another digraf pronounced as a Palatal nasal /ɲ/ (such as champagne in French, vinho in Portuguese, or gnocchi in Italian).
