She is the chief digital officer of OMD, a digital core of the agency, with more than 200 employees, focusing on digital intelligence, strategy, search and cross-platform partnerships.

Went digital when "Like a lot of my colleagues, I joined a start-up in the early '00s (it seemed like a good idea at the time). I was part of a group who learned to do everything while there. Want something faxed? Do it yourself. Need to find the cheapest corporate tax software? Look it up. Window shade fell down? Guess who's repairing it. It was a job for curious people who enjoyed learning about all aspects of the ad business by getting knee-deep into it — sink or swim."

Plusses of digital "If you understand the accountability the digital world yields, you elevate your analytics. Whoever can manage and use the data effectively has the most strategic advantage over any competitor."

And for a woman "Professionally, you can certainly get by without digital skills, but you'll be doing just that: getting by."

Digital at rest "I've picked up knitting. There's something so satisfying about taking a misshapen ball of yarn and making it into something… and not just any old something, but a useful object like a hat or scarf. I've also discovered a micro social network for knitters and crocheters — Ravelry. It's awesome."

Why the name Erin? "It was a last-minute choice by Dad who didn't agree with the name Heather, and it's a nod to my quarter-Irish heritage."

Latest guilty pleasure "I just became a member of Costco. I have a household of two, yet I still manage to spend an exorbitant amount EVERY WEEK. Who doesn't buy their dishwashing soap by the kilo?"
