What I'm looking for

I am seeking a data science leadership role focused on advertising and marketing measurement, experimentation, and privacy-preserving analytics that partners with product and media teams to drive measurable revenue growth.

I am a data science leader with 10+ years of experience building analytics and measurement programs for consumer-facing brands. I focus on advertising, loyalty marketing and digital experience measurement, and I partner closely with media, product, engineering and finance teams.

At Starbucks I led analytics for core revenue channels serving 50M+ customers and optimized about $500M in annual ad spend through experimentation, attribution and media mix modeling. I built a scalable experimentation infrastructure powering 100+ tests per year that unlocked significant incremental revenue and promotional savings.

I pioneered privacy-preserving measurement workflows and clean-room-compatible architectures to address ATT, cookie deprecation and evolving privacy regulations. Previously, I developed ad bidding algorithms and unified MMM/MTA approaches that improved ROAS and drove spend efficiency at Overstock.

I grow and mentor high-performing teams, deliver self-service analytics and causal methods, and apply the right statistical and product-focused tools to influence large-scale investment and go-to-market decisions.
