Timothy Lui
PhD candidate Stanford University
Timmy Lui is a 5th year, PhD Candidate at Stanford University working with Mineral-X. His research focuses on the application and development of data science methods for interpreting soil geochemistry in the context of mineral exploration. By combining geochemical analysis with computational tools, Timmy aims to improve how subtle geochemical patterns are detected and understood across large spatial datasets. His current work centers on developing GeoChemNet, a network-based visualization tool designed to enhance communication between scientists and reveal underlying geological relationships hidden within complex geochemical data.
2026 Agenda Sessions
Modern data science to accelerate discovery
This session explores how advanced analytical techniques, rooted in machine learning, network theory, and stochastic modelling, are transforming mineral exploration across Africa. Showcasing GeoChemNet, a novel approach to visualising geochemical datasets through network analysis, enabling geologists to identify meaningful outliers and patterns that traditional methods often miss. Participants will also examine how stochastic interpolation of flightline data is reducing false positives in geophysical surveys, improving the accuracy of subsurface targeting and saving millions in exploration costs.
