I am a Marie Skłodowska-Curie fellow in the Stellar Evolution (FQM292) group at the Department of Theoretical and Cosmological Physics of Universidad de Granada (UGR). From September 2021 I will join the Institute of Space Sciences (IEEC-CSIC) as a Ramón y Cajal fellow.

I received my PhD in Physics from Universitat Autònoma de Barcelona (UAB) in 2011 under the supervision of Dr. Ramon Miquel at the Institut de Física d'Altes Enegies (IFAE). After two years as a postdoctoral researcher at the Centro de Astrofísica (CENTRA) in Lisbon, I was a Fondecyt fellow working with Prof. Mario Hamuy at the Departamento de Astronomía of Universidad de Chile, later on a Research Associate at the Department of Physics and Astronomy and the Pittsburgh Particle Physics, Astrophysics, and Cosmology Center (PITT PACC) of University of Pittsburgh, and more recently a Marie Skłodowska-Curie fellow in the Stellar Evolution (FQM292) group at the Department of Theoretical and Cosmological Physics of Universidad de Granada (UGR).

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.

In this page you will find a brief summary of my research, a few documents I used for teaching at UAB and UGR, and my publications. My CV can be found here.

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).
