Sync posts from Notion
This article shows how blog posts can be synchronised between a GitHub repository and a Notion database. The idea is simple: write posts either locally in Markdown or directly inside Notion, while keeping both sides in sync. The workflow relies on a Notion integration and two GitHub Actions that handle synchronisation in both directions.

Part 1: Different distance measures in spatial interaction models
Distance in a spatial interaction model can mean straight-line separation, road-network distance, travel time, or broader travel cost. This tutorial compares the main options and explains when each is appropriate.
Part 2: Coordinate systems and Euclidean distance
Euclidean distance is easy to compute, but only if the coordinates are in a suitable projected coordinate system. This tutorial explains British National Grid, latitude/longitude, and a worked Euclidean-distance example.
Part 3: Network distance, shortest paths, and routing algorithms
Network distance measures travel along connected roads or paths rather than straight lines. This tutorial explains how shortest-path calculations work and introduces Dijkstra, A*, and other routing ideas.
Using the retail spatial interaction app
A practical walkthrough of the Shiny app for exploring grocery demand and testing a chain-based spatial interaction model across postcode sectors
Introduction to spatial interaction modelling
This tutorial explains the logic behind the spatial interaction model (SIM) used in the practical exercise. The aim is to understand how retail spending from different areas is distributed across competing stores.

[New paper] Supporting dementia carers in LMICs
Our new systematic review and meta-analysis on interventions supporting carers of people with dementia in low- and middle-income countries (LMICs).
Rethinking AI interpretability
Adapted from one of my postgraduate application essays, this article critically discusses Rashomon sets, interpretable modelling, and why simple explanations may be inadequate for high-stakes decisions.
Reflections on research culture
Adapted from one of my undergraduate essays on research integrity, incentives, competition, and cultural change in academia.
