An aerospace engineer from Barcelona passionate about robotic space exploration, autonomous and distributed space systems, optimization, and machine learning
I am currently a PhD Student at Stanford Aero&Astro, working on lunar Positioning, Navigation, and Timing at the Navigation and Autonomous Vehicles (NAV) Lab. In 2022, I completed my Bachelor's Thesis on dynamic resource management in satellite communications as a visiting student in the System Architecture Group at the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology (MIT). In parallel to my thesis research, our MIT team developed a mission concept for producing propellants on Mars from in-situ resources. I obtained a BSc in Aerospace Engineering and a BSc in Telecommunications Engineering at Universitat Politècnica de Catalunya (UPC) under the program offered by the Interdisciplinary Higher Education Center (CFIS). During my undergraduate studies, I collaborated with the UPC Nano-Satellite and Payload Laboratory on projects encompassing satellite constellations. I also completed an internship at Barcelona Supercomputing Center, working on a machine-learning distributed library for high-performance computing. During high school, I started the Gadget Robotics team, check it out here!
Soccer, skiing, scuba diving, and traveling are my favorite activities to take a break from work.
Research and Projects
Positioning, Navigation and Timing for Space Robotics
Navigation and Autonomous Vehicles – Stanford
Accurate Position, Navigation and Timing (PNT) will be crucial in the new era of Moon exploration. However, current vision-based methods are unreliable for the Moon's polar regions and permanently shadowed craters. I will be working on the architecting of lunar satellite navigation systems that take advantage of broadcasted Earth-GPS signals to provide PNT services and reliable communications.
Deep Reinforcement Learning for Trajectory Design in Cis-Lunar Space
Stanford Computer Science
There is a growing focus on populating the region between the Earth and the Moon, cis-lunar space. Finding low-thrust trajectories for cis-lunar space in real-time is a challenging problem, as traditional optimization methods require high computing power. Therefore, new approaches are needed to compute optimal trajectories and their control inputs in real time, improving spacecraft autonomy and efficiency.
Dynamic Resource Management for Communication Satellites
System Architecture Group – MIT
Modern high-throughput satellites with digital payloads and phased arrays have thousands of configurable variables. This makes it necessary for satellite operators to move from manual resource allocation to autonomous and dynamic resource management tools. The project aims at developing a holistic and AI-based approach to dynamically allocate resources for satellite constellations.
Martian In-Situ Resource Utilization from Subsurface Water Ice
Engineering Systems Laboratory – MIT
Fifty years after the first steps on the Moon, NASA is planning on sending crewed exploration missions to the Moon and Mars. Leveraging in-situ resources to produce propellants and consumables is a key enabler for these space exploration missions. The concept developed during NASA's RASC-AL competition consists of trucks working in tandems and focuses on reliability and scalability to produce large amounts of methalox.

Distributed Satellite Systems Simulator and Autonomous Operations
Nanosatellite and Payload Laboratory – UPC
Complex Earth Observation satellite systems are called to satisfy higher requirements than ever before, requiring specific simulation tools to plan their design and management. The goal of this project is to develop a Distributed Satellite Systems Simulator aimed at facilitating the conception and validation of new mission architecture concepts and advancing satellite networking and autonomous operations.
Machine Learning and Distributed Computing Models
Workflows and Distributed Computing Group – BSC
In recent years, machine learning (ML) has proven to be a breakthrough in solving complex problems. However, ML libraries are difficult to set up in high-performance computing clusters. In this project, I developed ML algorithms for the Distributed Computing Library, a Python library built on top of PyCOMPSs, a model and runtime for distributed infrastructures, such as Clusters and Clouds.
