02 / Trajectory

Academic and research path

A compact view of the research, mathematics and applied learning experiences behind my work.

Experience

  • Jan 2026 - July 2026

    Graduate Researcher

    Brain Circuits and Behavior Lab (IDIBAPS)

    Graduate researcher studying the fluctuations in behavior on 4 different tasks in mice through Hidden Markov models. This project was tied to my Master's Thesis. It aims to understand the underlying strategies that mice use to solve tasks and how these are shaped by the effects of NMDAr hypofunction. A python package was developed with the used models and is published in pypi under the name glmhmmt.

  • Jul 2024 - Dec 2025

    Internship

    Brain Circuits and Behavior Lab (IDIBAPS)

    Internship conducting experiments with mice using an automated behavioral system (Training Village) to study the effects of anti-NMDAR encephalitis on working memory. Tasks included statistical analysis with Generalized Linear Models (GLMs) and the development of a decision-making model as part of my Mathematics Bachelor’s Thesis (TFG). The project combined data analysis and mathematical modeling to provide deeper insights into the dynamics of cognitive processes.

Education

  • Sep 2025 - Present

  • Sep 2021 - Jun 2025

    Degree in Mathematics

    Universitat Politècnica de Catalunya (UPC)

  • July 2023

    Summer Course (Applied Machine Learning to Solve Real-Life Problems)

    Universitat Politècnica de Catalunya (MESIO UPC-UB Summer School)

    Conducted by a lead data scientist at N26. The course focused on financial problems, such as credit risk, fraud detection and default rate prediction. A kaggle competition centered on predicting default rates of businesses was held at the course, where I achieved the winning position.

  • Jul 2021

    Summer Course (An introduction to image processing)

    Institut de Ciències Fótoniques (ICFO)

    A two week course on image compression algorithms in Matlab and information theory held at ICFO in the Theoretical Quantum Nano-Photonics Group.

  • 2022

    Participant at the program. LYISF is a two-week science program held at Imperial College of London and the Royal Geographical Society with participants from over 70 countries. I attended lectures on a variety of science topics and visited research centres such as the Oxford Nuffield Department of Clinical Neurosciences.

  • Jun 2019 - Sep 2022

    Youth and Science

    Fundació Catalunya La Pedrera

    Selected to participate at the programme Youth and Science, managed by Fundació Catalunya La Pedrera. A three-year programme to encourage scientific vocations of fifty talented young people with a drive to research. Funded to participate in LIYSF and the ICFO summer course (An introduction to image processing).
