About

I study companies, markets, and competitive systems.

I look for the gap between what a company says and what its data shows in public filings, ad libraries, hiring patterns, trademark records, and customer evidence.

The aim is to turn scattered public evidence into a clearer view of how a company actually competes, where it is vulnerable, and what may change next.

Selected research is published here.
