Hi, I’m Mateo.
I build ML systems for complex environments.
I’m a Senior Machine Learning Engineer at Vu.City and an Honorary Research Fellow at UCL.
I specialize in spatial and graph-structured data, moving between academic research and production engineering. I build models that don’t fall apart the second they hit production, even when the underlying data is a total disaster.
I have a research background in Network Science and Urban Analytics (PhD, UCL / Alan Turing Institute), where I studied how network structure and information shape human behaviour in cities. Since then, I’ve spent much of my time bridging the gap between research and production: designing, building, and deploying data and ML systems inside practice-driven environments.
I have spent my career applying that rigor to industry. Previously, as an Associate Partner at Foster and Partners, I led the deployment of data-driven tools that influenced urban design at scale. Before that, I developed transport algorithms at SignalBox.
My work is defined by synthesis: taking ideas from papers, prototypes, or whiteboards and translating them into robust, scalable systems across data pipelines, modelling, and product integration. I’m comfortable operating end-to-end, from experimental work to engineering decisions and stakeholder alignment.
I’m especially interested in problems involving:
- spatial and graph-structured data
- long feedback loops and real-world constraints
- systems where technical choices meaningfully shape decisions

The Alpha-Blending Problem: Semantic Segmentation in 3D Gaussian Splatting
A survey of why making 3D Gaussian Splatting semantically meaningful is harder than it looks. Covers the core technical challenge — alpha-blending ambiguity at object boundaries — and the three paradigms that have emerged across the CVPR, ECCV, and ICCV 2024–25 literature: feature-field distillation, 2D-to-3D lifting, and identity-centric methods.
Spatial Interaction Models
An in-depth exploration of spatial interaction models with interactive visualizations, covering their theoretical foundations, mathematical formulation, and practical applications in urban planning.
Transport Networks
Interactive exploration of centrality measures of the metro systems of London, New York, Chicago, and Santiago de Chile. Time-weighted graphs constructed from publicly available GTFS data.
