My research trajectory includes a stage as a PhD student at the Center for Biotechnology (CSIC) and the Center for Astrobiology (CSIC-INTA), where I developed my doctoral thesis titled "Influence of initial diversity and environmental change pattern on the evolution of bacteriophage Qβ" under the supervision of Dr. Ester Lázaro. This research was conducted almost entirely at the Center for Astrobiology, where I explored the evolutionary mechanisms of a model virus in extreme environmental conditions. This experience provided me with a deep understanding of evolutionary processes in viruses and strengthened my skills in molecular biology techniques, including sample preparation, sequencing, and bioinformatic analysis. As a postdoctoral researcher, I have applied my skills in next-generation sequencing (NGS) techniques to analyze the genomic dynamics of SARS-CoV-2, as well as its adaptation to different environmental conditions and selective pressures. Additionally, I have actively contributed to the communication and dissemination of our research results through seminars and the preparation of scientific articles. My skills include proficiency in bioinformatic analysis tools, as well as the interpretation of massive sequencing data to understand the evolution of viral populations. Furthermore, my interdisciplinary training in fundamental physics and biophysics has provided me with a solid foundation to address complex issues in virology from an integrative perspective.
