I combine ideas from different fields and use AI to put them to use.
For that to work, AI has to be dependable. So I work on it from both sides: building with AI, and making AI that can be depended on.

Counted When Promised
How much of rich countries’ climate finance actually arrives?
Five minutes on the headline climate-finance total, which mixes promises with payments, and what it would take to check each promise against what was paid. Every figure on screen names its source.
Made on one machine with AI tools. The narration is my voice, cloned.
A public record of how each country reads its climate-finance obligations. Each reading is written as a formal model, so anyone can check what it commits that country to. It starts with one investigation.
In Parkinson’s disease, a circuit deep in the brain locks into a strong 15 to 30 Hz rhythm, and its neurons both fire faster and fire in bursts. Since the two changes arrive together, nobody could say which one drives the rhythm. We separated them in a simulation of 3,000 neurons. How fast one group of neurons fires decides whether the rhythm appears. Bursting matters only when the circuit sits near the edge of rhythm, where it can tip it either way. That may explain the short bursts of rhythm seen in recordings.

Neurons differ in how they fire: some at a steady pace, some in bursts. We built a model neuron whose firing pattern can be changed without changing how much it fires, and asked whether those patterns change what a whole network of neurons does. The answer depends on the state the network is in. Across most states the patterns make no qualitative difference. Near certain tipping points they can start or stop a rhythm. When each neuron’s pattern also depends on the network’s activity, the network’s response to an input comes to depend on its recent history.
