Playful questions. Rigorous answers.

I build models, experiments, and tools to understand how people—and machines—make sense of the world.

Illustrative model

Same evidence. Different decision.

Move a criterion. The response probabilities change; fixed discriminability does not.

Equal-variance distributions. The five movable lines are response criteria.

d′ = 1.55 · criteria shift responses, not discriminability

Selected work

Questions with somewhere to go.

Three finished projects where a claim becomes a tool, a workflow, or a picture.

Currently investigating

Can padding change what a model learns?

I’m testing whether padding-sensitive normalization changes audio-classification metrics in a small DistilHuBERT model. The study compares ordinary and masked normalization under two padding conditions.

Recent notes

Small distinctions with large consequences.

Notes are short, but they keep the measurement attached to the question.

About and contact

Let’s talk about models, experiments, and useful tools.

My background spans psychology, experimental methods, statistics, data science, and machine learning. I turn research questions into models, visual explanations, and tools that other people can inspect.
