PhD Student in Computer Vision

I am a PhD student in Computer Vision at the Institute of Robotics and Industrial Informatics (IRI, CSIC–UPC) in Barcelona, advised by Antonio Agudo. My work sits at the intersection of computer vision and computer graphics, where I study how to turn ordinary images and video into faithful, editable 3D representations of the real world.

Broadly, I am interested in 3D scene understanding: reconstructing scenes, recognizing and segmenting the objects within them, and decomposing them into clean, manipulable parts that can be edited, relit, or reused. I work with mesh and splatting representations, multi-view segmentation, and generative models for 3D content, always with an eye toward connecting what a camera sees to the underlying structure of a scene.

Before starting my PhD I worked as an AI engineer and as a research assistant, on projects spanning 3D simulation, synthetic data generation, and interactive graphics. I also teach as a teaching assistant at UPF, for the undergraduate Computer Graphics and Electronic Games courses, the latter where students learn to code their own videogame.

Outside research, I am a videogame and football lover and an amateur weightlifter, and a fan of self-hosting, Linux, and open-source software. I enjoy building systems as much as studying them, and I am always happy to discuss research, 3D vision and graphics, or potential collaborations.

Research

My work sits at the intersection of computer vision and computer graphics, focused on 3D scene understanding: reconstructing scenes, segmenting them, and decomposing them into clean, editable objects.

I am interested in bridging 2D perception and 3D structure so that real-world scenes can be turned into faithful, manipulable 3D representations. I work with mesh and splatting representations, multi-view segmentation, and generative models for 3D content.
