Research direction and evidence

Research direction · Spatial intelligence

How can intelligent systems understand a world they only partly observe?

My long-term direction is spatial intelligence: helping intelligent systems understand the physical world—its properties, relationships and changes—well enough to reason and act. I approach this through observation. Sensors provide partial, noisy and different evidence; my published work studies how to recover useful physical quantities from it. Maintaining that understanding over time and using it in decisions are the next questions.

Partial
A sensor observes only what its viewpoint and physics allow.
Different
Two modalities can observe the same thing without measuring the same property.
Changing
An estimate must be reconsidered as the world and its observations change.

Toward spatial intelligence

Research roadmap

My published work establishes task-specific foundations in sensing and representation. Current research brings time and context into view. The roadmap extends from these results toward persistent physical-world understanding; its later stages remain open research questions.

  1. 2022–2023

    Published foundations

    Recovering a signal

    Biomimetic sonar and mmLeaf introduced me to indirect observation: finding structure in echoes and measuring leaves with radio waves.

  2. 2024

    Published foundations

    Learning from complementary views

    Hydra combined radar and camera observations. That made the representation—not simply the choice of sensor—the next question.

    Making the representation useful

    Proteus studies what a radar can learn from a camera. Adonis asks how to measure degrees of wetness, with calibration for field conditions.

    From a snapshot to a continuing record

    Driving assessment motivates a shift from isolated measurements to behavior understood over time and in context. The public preprint sets out design principles and research opportunities; a completed monitoring evaluation remains to be established.

    Future agenda

    Persistent understanding for reasoning and action

    Connect physical estimates across time, revise them when evidence changes, and determine when they can support a decision. These are the next research goals, building on the sensing foundations above.

Future agenda

Understanding the physical world over time

I want to build a research program in spatial intelligence that connects observation, physical representation and persistent understanding. The goal is for systems to maintain an account of what is happening, what is uncertain and when the evidence is sufficient to reason or act. Three open questions define the work ahead.

Understanding with incomplete evidence

What physical state can we infer—and what must remain unknown?

Develop representations that connect heterogeneous observations to physical quantities and make uncertainty explicit.

Starting from Hydra, Proteus & Adonis

Understanding that lasts

How should a system revise its beliefs when observations stop or the environment changes?

Study continuity, change and uncertainty over time, with evaluation that exposes missing observations and shifting conditions.

Motivated by field sensing & contextual driving assessment

Understanding worth acting on

When is an estimate reliable enough to support a decision?

Connect model reliability to the consequence of an error, including when a system should ask for more evidence or defer to a person.
