01 — About

Background

An MSc in Macroeconomics and Econometrics from the University of Nottingham took me into media — Zenith, OMD and Mindshare — moving from analyst to senior consultant along the way.

Every strategic recommendation is backed by data — whether that's a Marketing Mix Model or a conversion optimisation programme, I work with statistical rigour and a sharp focus on the business outcome.
