Explain the pattern.
Applied mathematics gives complicated systems a language—from Fourier series to financial models and image reconstruction.

Point of viewBuild clearly. Learn in public.
01 / The through-line
Find the hidden structure. Make it visible. Put it to work.
A yield curve, a basketball dribble, an image, and a marketing workflow look unrelated until you ask the same question of each: what pattern is underneath?
Leith’s published work explores the models. His work in AI explores what happens when those models become useful tools.
The story so farOne practice, three lenses
Curiosity with an output.
Follow the change.
Movement is data. One published study turns the rhythm of a basketball dribble into a periodic signal that can be modeled.
Build the system.
AI becomes valuable when it leaves the demo and enters a real workflow—clearly mapped, tested, documented, and improved.
Featured field note
The Marketing Mechanic.
A whiteboard walkthrough of how a marketing system fits together—part explanation, part build log, and a starting point for what comes next.
Research, 2024–2026
Five papers. One visible pattern.
The subjects move from periodic signals and quantitative finance to computer vision. The method stays consistent: make a difficult system legible.

The working loop
Think in public. Ship the proof.
Observe
Start with the real system, not the fashionable abstraction.
Model
Map the variables, relationships, and failure points.
Build
Turn the model into a tool someone can actually use.
