I am a PhD student at the Univesity of Zaragoza since November 2019, in the Robotics, Perception, and Real Time Group, supervised by Ana C. Murillo.
My PhD studies are mainly focused on efficient Computer Vision and Deep Learning for video data processing. Building high-performance Machine Learning models that are able to run with minimal computational resources and learning from low-scale datasets, is the way to bring Artificial Intelligence to many applications and use cases.
My research includes tasks such as Object Detection, Action Recognition, Depth Estimation, and Semantic Segmentation. To this end, I have not only worked with supervised learning, but also with contrastive, self-supervised, semi-supervised, and multi-modal learning.
In the development of my PhD thesis I had the opportunity to join the University of Lisbon (Institute for Systems and Robotics) for a 4-months research stay, and Amazon-Berlin as Applied Scientist for a 4-months internship.
