Hi! 👋 I am a first-year PhD student in the REALISTIC GRAPHICS LAB at under the supervision of Prof. WENZEL JAKOB. Prior to joining EPFL, I studied a Bachelor's degree in Computer Science and a Master's degree in Biomedical Engineering, both at UNIVERSIDAD DE ZARAGOZA. During that time and after, I have been a junior researcher in the GRAPHICS & IMAGING LAB under the supervision of Prof. ADOLFO MUÑOZ and Prof. ADRIAN JARABO.

My work revolves around the different aspects of physically-based and differentiable rendering, including light transport and reconstruction, with mention on both transient and computational imaging. Nevertheless, I’m always looking forward to learning something new!

Automatic generator of a webpage with comparisons of renders with support of visualizer (including insets), runtime-generated several error metrics, video player with slider and error metric table.

    LIGHTNING: Physically-based Renderer on CPU

    Fully CPU-parallel Physically-based renderer featuring both unidireccional Path Tracing and Photon Mapping. As additional features, next event estimation, acceleration structures, participating media and several BRDF. This project was awarded with a honor mention and was the winner of the best looking render competition.

      Telegram bot that allows to direct query, fuzzy search or GPS-locate stops of both bus and tram in Zaragoza. Allows to track easily times than the original webpage of the city council.

        J.A.R.V.I.S: Discord Bot based in NLP and Voice Control

        Fully-fledge Discord bot with support for answer queries both writen and speaked that can run in low-tier cloud systems. Added voice control is a marvellous when you are ingame and need to manage something from the server (or change the playlist).

          CRISTOBAL: Mindstorm-based fully fledge robot OS

          The system features dynamic path planning and awareness of the surrounding world by combining odometry of the wheels, gyroscope, compass and sonar. To reduce shift in data, it features a sensor-fusion approach using Extended Kalman Filter, allowing to increase the accuraty of the position. This project was awarded with the mention of honor as the best approach.

            LITTLE-LENG: Full AST Compiler for Custom Language

            Full compiler using JavaCC with a custom-made abastract syntax tree. Compiler features constant-time aggregation of operations, strong typing, usefull error/warning messages (including suggestions of misspell names), removal of unused parameters, optimization of math operators and emojis.

              Cross-platform bibliography manager with a focus in usability and management of larger libraries. Future features will support sharing between users and tentative ML approach to discover and extract information.

                BASKET-VR: Assignment for VR Course

                Assignment for the VR Course where the students learn about movement in VR enviorements and how to interact with the world using controllers. To make it fun, students end playing virtual basketball.

                  Fourier Classifier based on CNN Arquitecture

                  Improved solution that changes the net architecture to use Convolutions, allowing the system to work with crops of the signal instead of the full data. This solution was originated as an improvement over previous solution to allow its use in realtime situations (as games livestreams).

                    UCODE 2019 - Fourier Classifier ML

                    Our project submitted to the hackathon competition where we solved the Adidas Advanced Division's problem about classifying movement sequences using Machine Learning applied in frequency space. We achieved a 94% accuraty.

                      UCODE 2018 - Indoors Beacon-based Location

                      Our project submitted to the hackathon competition where we designed and implemented an indoors solution for tracking users when GPS is not an option. Our solution works with Bluetooth technology and allows to guide users given their positions and preferences.
