About. Currently leading signal evaluation at a fintech.
Fields I find fascinating are decision theory, epistemology, and cosmology. My favourite authors are Deutsch, Isaacson, and Feynman (cliché).
I studied Systems Design EngineeringSystems Design EngineeringA co-op program combining software, mechanical and electrical engineering with design and human factors.x* equals argmin over x in F of the expected value of C of x and xi.Coursework ranged from modelling and optimization to statistics, pattern recognition and scheduling.See an example class profile at uWaterloo.

Direct Atomics: A Post-Mortem
Direct Atomics built an equivariant GNN to accelerate DFT, reducing simulation time from months to minutes. Challenges included niche markets, resistance to drag-and-drop tools, and in-house/open-source competition.
Built
- Direct AtomicsDirect AtomicsWe trained a 13.8M parameter equivariant eSCN model on Alexandria's DFT data to estimate energies and forces from atomic structures.Screening materials faster wasn't enough. Semiconductor customers had billions invested in making their existing materials work. Read the post-mortem here.
Neural networks for atomic energies and forcesPost-mortem - Modern RelayModern RelayAn agent works out how to find something in the company's data. Save that query so the next agent doesn't have to work it out again. Agents can propose changes to the data model too. New facts go onto branches for review, so mistakes can be discarded before they reach the shared graph. The company owns the data and its definition.Reusable queries and reviewed changes to company dataRaised $3M

Believe
- Mouth closed, don't get fed.
- Desperation never served anybody. Suffering is a choice.
- Life is too short to play zero-sum games (e.g. status).
- Kindness isn't niceness. Signaling virtue is a vice.
- Character is grace when the chips are down.
- Grit is a superpower, but so is quitting.
- Be a hyperrealisthyperrealistAppreciate every reality, even the harsh ones. Despise impractical idealism.Dreams matter, but the people who build great things aren't idle dreamers. They're grounded in reality, understand cause and effect, and use principles to get what they want.. Dreams + Reality + Determination = A Successful Life.
