Frame the decision
Separate facts, assumptions and open questions before choosing a method.

How I work
Method follows the decision.
I start with what a team needs to decide, then build the smallest credible evidence system that can reduce uncertainty.
Build the evidence
Combine qualitative depth, surveys, behavioral data and UX metrics where each adds a distinct answer.
Translate, don’t dump
Turn findings into product requirements, trade-offs and testable directions.
Make knowledge reusable
Use traceable repositories, taxonomies and AI-enabled workflows so evidence survives the study.
AI-enabled research
Faster research operations. The same evidentiary standards.
I use AI for synthesis support, documentation and knowledge retrieval — grounded in verified research records. Human judgment still frames the question, challenges the output and decides what the evidence can support.
