About

Leading marketing and advertising effectiveness researcher, author and consultant exploring how creativity helps brands grow across modern media. I studied medicine, then accidentally fell in love with marketing and behavioural science. After helping grow some of the world's biggest FCMG brands for 6 years, I joined the effectiveness platform System1. We build advertising effectiveness tools and data to help marketers make more decisions with more confidence. I build global partnerships with media owners, agencies and effectiveness bodies to scale how our tools and data are used. And to create globally awarded advertising effectiveness thought leadership. I've personally researched and published (with my amazing team): research on creative consistency with the IPA (Compound Creativity), the playbook for audio creative effectiveness with Radiocentre (Listen Up!), proof that and guidance on digital media and short-form building brands with TikTok and Pinterest, guidance on improving the effectiveness of outdoor advertising with JCDecaux, and a new global playbook for advertising effectiveness with Effie Worldwide (The Creative Dividend). Amongst other publications. I regularly do keynotes at the industry's biggest events, consult for the world's largest brands and agencies, write a weekly column in the Drum, and reach about 1mil people a week on LinkedIn. As Chief Growth Officer, I essentially act as a partner at System1 responsible for the advertising research business. Defining our proposition (products and consultancy), strategy, investments, thought leadership, vision, etc.
