Applied AI · Founder, infinitesimal.ai
I lead applied AI where it meets people. AI does the generation; I own the direction, the taste, and the decisions.
The work below is mine, hands on and end to end, because I do not think you can direct this from a slide. I am the founder of infinitesimal.ai, and before any of this I was an associate professor for nine years, department chair for five.

The site you are reading this on.
An AI version of me in a rendered 3D apartment, with a fully procedural San Francisco outside the window that tracks the real clock and the real weather. A conversational avatar with voice, lip-sync and expression; recommendation systems for books, film and music that learn from what you actually do; and a living scene built shader by shader. Next.js, Three.js, MongoDB, and large language models.
I show it because it is the whole argument in one place: what one person directing AI agents can actually produce, where it goes wrong, and what has to be true before anyone should trust the result. Scoping that, and knowing what to throw away, is the part that does not get solved by hiring more engineers.

Most of this site was built in collaboration with AI coding agents, and every line of it was reviewed, tested, and often deleted by a human. That split is the point, and it is the management problem too: the generation is cheap now, the judgment is not, and the people who can tell the two apart are the ones worth building a team around.
AI does the generation; I own the direction, the taste, and the decisions. Knowing which is which is the job.
AI output is confidently wrong in ways that look right. The interesting work is building habits that catch it.
People trust AI appropriately when they can see how it works. Legibility is a feature, not a leak.
The full story of building this site that way, including where the AI went wrong and how it got caught, is in How This Was Built. What the avatar actually receives, keeps and gets wrong is in the model card.
Short pieces about putting AI in front of people, mostly about the gap between what a system can do and what people believe it can do.

A charming AI is not the same thing as a trustworthy one. How this site tries to earn exactly as much trust as it deserves, no more, and why that is a design problem rather than a disclaimer problem.
Case study · August 2026
Most of this site was written by AI agents. All of it was directed, reviewed, and pruned by a human. What got delegated, where the AI was confidently wrong, and the habits that caught it.
Invite me for a talk, a keynote, a guest lecture, a podcast conversation or an interview about building with AI. I can show the work: directing agents, designing conversational interfaces, and catching the mistakes that look right.
Behind it, 84 talks and papers over thirteen years as an academic, a keynote, a Governor’s Teaching Fellowship, four books (one as author, three as editor) and an interview podcast with forty-nine guests. The speaking page has the record, three talk subjects and an invitation form. I am open to board and advisory seats too.
I am looking for the role where applied AI is the strategy rather than a side project, and someone has to own it: set direction, build the team, and answer for what the system does in front of real people. If that is the seat you are filling, this is the right door.
The avatar is fun, but there is a real person here too. Email is the surest way to reach me.
