08193 Barcelona, Spain

I am a PhD student in Computer Science at the Computer Vision Center (CVC), Universitat Autònoma de Barcelona, under the supervision of Alexandra Gomez-Villa, where I focus on color understanding in multimodal models. I also collaborate with Jesus Malo at Universidad de Valencia on generative models and vision science. I hold a Master’s degree in Engineering and a Bachelor’s degree in Electronics Engineering, both from Universidad de Antioquia. My master’s work focused on the intersection of domain adaptation, wildlife monitoring, and multimodal learning, with a particular emphasis on bridging foundation models and real-world computer vision applications. I have completed research internships at Télécom Paris working on domain adaptation for biodiversity monitoring, and at Universidad de los Andes focusing on wildlife image segmentation. I have been awarded the NVIDIA Academic Grant.

I serve as a reviewer for journals such as IEEE Transactions on Biomedical Engineering and EURASIP Journal on Image and Video Processing, and conferences such as NeurIPS 2025 Workshop NPGML and ECCV 2026.

Mar 09, 2026 Our paper “WildIng: A Wildlife Image Invariant Representation Model for Geographical Domain Shift” is now published in the International Journal of Computer Vision (IJCV). This work is based on a large part of my master’s research. In the paper, we study the problem of geographical domain shift, where models trained in one region fail to generalize to others.
Jan 29, 2026 Excited to begin my PhD in Computer Science at the Computer Vision Center (CVC) 🇪🇸 under the supervision of PhD. Alexandra Gomez-Villa. My research will focus on color understanding in multimodal models, exploring how to advance the scientific understanding of color perception. 📍 Barcelona, Spain
Feb 28, 2025 Our paper “CATALOG: A Camera Trap Language-guided Contrastive Learning Model” has been selected as an oral presentation (top 8%) at the IEEE/CVF Winter Conference on Applications of Computer Vision (WACV) 2025! 🎉📷🧠
