In their own line of work

Joseph started in physics at UC Berkeley, then spent three years at Lawrence Berkeley National Laboratory on nuclear physics, high-energy accelerator physics, and radiation imaging. He went on to Cornell for a PhD in Biomedical Engineering on nuclear fusion and cancer research, funded as an NSF Graduate Research Fellow and a Sloan Fellow. From there he moved into finance: Bridgewater Associates, where he worked across investment engineering, knowledge engineering, product engineering management, and finally Manager of Technology & Intelligence on AI-driven equities research and algorithmic decision-making.

In 2019 he co-founded Vivun and spent the next seven years as Chief AI Officer researching how AI teammates can actually achieve structured reasoning, durable memory, and autonomous action. In parallel he founded Battery CI, a systematic quantitative FX hedge fund, and Openmind, a research bet on causal inference for general AI. In May 2026 he became Chief AI Officer at Hudson Bay Capital Management LP in New York, applying the same research discipline to institutional asset management. He continues to advise PromptID on K-12 AI for competency validation, Appian Water on sustainable water access, and AGMI Group on AI tooling for pharmaceutical consulting.

What Joseph brings to a Wavect build is rare. The research-grade understanding of what a model can actually do, the institutional discipline to ship it without overselling, and the leadership track record of engineers following him from company to company. He is the person we call when a spec says the word “AI” and someone needs to translate that into what is shippable in six weeks versus what is a six-quarter research program.

03  ·  WHEN WE BRING THEM IN

Where Joseph Miller, PhD plugs into a Wavect engagement

Wavect builds the product. When a build crosses into a domain that exceeds our own bench, we bring in the specialist who already lives there. This is the brief for this one.

  • AI agents that hold up in production

    When a build needs agents with structured reasoning, durable memory, and autonomous action (Vivun's actual research domain for seven years), Joseph sense-checks the architecture before we ship a demo that breaks in week two.

  • Quant-grade AI for finance and trading

    Hudson Bay, Bridgewater, Battery CI. When a fintech, treasury, or trading build needs an ML model that survives institutional scrutiny (model risk reviews, backtest integrity, regulator-facing explainability), Joseph pressure-tests it before the model goes live.

  • Causal inference, not just correlation

    Openmind was a multi-year bet on causal inference for general AI. When a product team is about to ship a feature built on a correlation that will not hold under real-world distribution shift, Joseph names the gap. We bring him in early.

  • Research-to-product translation

    Cornell PhD plus seven years shipping production AI. When the technical literature says X is possible but the engineering team cannot tell whether it ships in six weeks or six quarters, Joseph reads both sides and gives a real answer.

Working with Joseph over the years has been nothing but a pleasure. Our working relationship is one that I strive to achieve with all of my partners.

Let me be very clear about something though. Whilst I have found and placed some incredible people onto Joe's teams over the years, they have chosen to follow him from company to company because he's a brilliant leader. He genuinely cares and he treats everyone as an individual.

Joe gets my highest recommendation as a person, a partner, a Leader, a teammate and a friend.

If you are lucky enough to get the chance to work with him, it will be nothing but a fantastic experience.

It was a privilege to have Joe as my manager. He built a team filled with people that are talented, hard-working, and fun. Besides being creative and inspirational, Joe is the kind of leader that you'd want to befriend and hang out with.

Joe's creativity and vision are matched only by his empathy for the people he works with. He leads by doing, constantly challenging those who work for him to level up while giving you the rope to challenge and even surprise him. If you work with or for Joe he will invest in your success and development as if it were his own. It was a privilege to work with him.
