    Student Researcher

    ๐ŸŽ“ Internship program MASTER+UB. Grant offered by University of Barcelona to capt students to study a Master's degree and encourage scientific vocations in a research group. In my case, in the holomorphic dynamics research group of University of Barcelona. This program enables me to work on my final master's thesis in the field of holomorphic dynamics, specifically focusing on root finding algorithms.

    Choir Singer ๐ŸŽค๐ŸŽถ

    <strong>Choir Singer ๐ŸŽค๐ŸŽถ</strong>
    Every Tuesday, from 19:30 to 21:00, I sing with the choir Cor Jove del Orfeo Sarrianenc๐Ÿ’š๐ŸŽถ. This experience helps me connect with my more vulnerable and human side. The choir, conducted by Gerard Ibaรฑez, is a semi-professional group that performs a wide range of music, from Queen to The Lion King: The Broadway Musical.

    <strong>Beach Volleyball ๐ŸŒŠ๐Ÿ</strong>
    Every Wednesday and Thursday afternoon, I train beach volleyball๐Ÿ’™. Sports have always played a crucial role in my life. I trained in water polo for more than 10 years, but due to compatibility issues, I switched to beach volleyball. It has now been over 5 years that I've been playing this amazing sport at a semi-professional level.
