AI control that labs can say yes to

BlueDot Impact · Technical AI Safety Project

AI labs can have a trusted model watch their most capable one and step in when something looks off. Few do it well, and cost is why: at frontier scale, even 1% overhead runs into billions.

We're running the first like-for-like test of AI control methods: the same attackers and the same models for every method, scored on safety, usefulness and dollars. The result is a map of the best protection money can buy. Next, we take on the open problem of what to do once a model gets caught.

Explaining AI to people who don't work in it

The Pivot's Archive · Substack

Most people will live with AI's consequences without ever reading a research paper. I write for them: no hype, no doom, just enough to form their own view.

Every essay also gets a hand-built, scroll-through version in cut paper.

Pivotr Studio

My web studio for small businesses

Building software keeps getting cheaper, so a local business shouldn't need an agency budget to get a good website.

Clean, fast websites with no ongoing fees, and one free build every month for a non-profit.

Tools I couldn't find, so I built them

The alternatives were paid, or didn't exist

All of them are free and private by default. Where it can, your data stays in your browser, and there's no account to make.

Zara LM: sovereign AI for government

AI Engineer · Phoenix ICT Solutions

Secure AI for Australian Government teams, running on government-controlled infrastructure where no prompt or document leaves the environment. It answers with citations from trusted sources and drafts briefings and analysis for a human to sign off.

Voice AI for women artisans in rural India

Engineering for Change Fellow · Resham Sutra

Resham Sutra's marketplace connects rural women textile producers with buyers, but a text-heavy app shuts out anyone who struggles to read it.

I built a lightweight voice assistant that runs on low-end phones, in Hindi and Marathi, so they can run their business by speaking.

AI Change Detection Platform

Mechatronics Engineer · Geodrones Australia

Fused camera and LiDAR on the drone itself to detect changes across a site in near real time. I also built secure in-flight task swapping and the battery management firmware.

• Demoed to industry leaders at October Sky 2024

Navigation that holds up when GPS lags

Honours research · ANU

Implemented a new observer for drone state estimation when GPS readings arrive late: the first with almost-global stability guarantees.

• Published in the European Journal of Control
• Presented at the ArduPilot Developer Conference 2023
