Welcome.
I am a doctoral candidate at the Institute for Biological and Medical Engineering (IIBM) at UC Chile, working at the Center for Biomedical Imaging (CIB) and the Millennium Institute for Intelligent Healthcare Engineering (iHEALTH).
My work sits at the intersection of physics (Magnetic Resonance Imaging), scientific computing (Julia & Python) and artificial intelligence (Deep Learning & Optimization). I specialize in MRI simulations, sequence design, and optimization, but I also have experience in Computer Vision, Brain-Computer Interfaces, and Engineering Education.
I always welcome collaborations, questions, or just a chat about science, code, or anything in between. Beyond academics, I enjoy photography, music, web development, coffee brewing, and gluten-free baking. Feel free to reach out.
Short Bio
Originally from Bolivia, I served as a full-time university lecturer and researcher at Universidad Católica Boliviana (UCB) before joining the Institute for Biological and Medical Engineering (IIBM) at UC Chile, working at the Center for Biomedical Imaging (CIB) and the iHEALTH Millennium Institute in Santiago, Chile.
Beyond traditional research, I am deeply invested in interdisciplinarity, open science, collaboration, and knowledge sharing. I program extensively in Julia and Python. I contribute actively to MRI Together and CAMERA from ESMRMB, the ISMRM Latin American Chapter, and the IEEE P2731 Working Group on Brain-Computer Interfaces Unified Terminology.
In industry and technology transfer, I have worked on embedded systems and full-stack solutions (Natural Bolivia), data science (Entel PCS), and enterprise AI assistant development with multi-agent LLM evaluation at Generadora Metropolitana, alongside NLP initiatives at Bci. I also participate as a co-founder and architecture lead at Recursa Labs, where we build applied AI solutions, cloud architectures, and intelligent workflows.
