When I was twelve, my mom started buying me a magazine called Conozca Más — "Know More." Every month, without fail, she never missed one.

I had no idea what research was. But those pages were full of discoveries about science, psychology, the future, how people think and why they buy things. And at the end of every story, the same words: "researchers at Harvard," "a study from UCLA," "scientists at the University of Michigan."

I didn't know what those people did, or how to become one of them. But somehow, without understanding any of it, I wanted to be one.

Life went on. The dream faded. I didn't know what a Ph.D. was until I left Ecuador for my MBA. By then I had forgotten I ever wanted to be a researcher at all.

It was my wife who saw it before I did, and pushed me toward the Ph.D. when I couldn't see the path myself. Leaving wasn't easy — my mom was one of the few who didn't want me to go. But my wife and my kids came with me, and they endured the hard years right alongside me. The dream became ours.

Now I am a researcher. I publish articles about how people feel, choose, and connect with brands — from a university in the United States. And somewhere, I hope, a kid is reading something with my name in it, dreaming of a path they don't yet know how to find.

This one's for my mom, who first made me wonder. For my wife and my boys, who made it real. And for that kid.

The effect of brand identity–cognitive style fit and social influence on consumer-based brand equity

With Francisco Guzmán. Rational brand identities resonate more with analytic thinkers; emotional identities with intuitive ones. But what really drives brand equity is whether consumers identify with or internalize the brand's values — not just whether the message is emotional or rational.

The anatomy of a rivalry: the role of resentment in the development of brand attitudes

With Blair Kidwell. Rivalries are fueled by resentment rooted in perceived injustice. When consumers see one brand treat another unfairly, they side with the underdog. A past-focused mindset intensifies this; a future focus attenuates it.

The rivalry effect: emotional intensity and confrontational interactions on purchase intentions

With Blair Kidwell. A rivalry is defined by two factors: emotional intensity and confrontational interactions. Together they generate brand interest, which drives purchase intentions — but only for consumers with a high need for external stimulation.

Investigating the effects of political correctness in social marketing messaging

With Guzmán, Ahmad, Strutton & Kennedy. Politically correct health messages are more persuasive than politically incorrect ones. The effect works through consumers' attitudes and perceived manipulative capacity, and is strongest in gain-framed messages.

When and why consumers prefer androgynous choices

With Niusha Jones & Blair Kidwell. Consumers prefer choices that pair a feminine brand name with a masculine design (or vice versa) because they fulfill both agency and communion motives. Traditional gender norms moderate this preference.

💡 ideas
working thoughts — seeds for future research

can a brand feel betrayed?

Consumers anthropomorphize brands — does that extend to perceiving relational injury when a rival "wins"? What are the downstream effects on loyalty?

the moral economy of the tip

Tipping is a social contract and identity performance. How do platform-imposed prompts disrupt this — and who bears the cost?

retail power as a persuasion variable

As DTC grows, brand-retail power shifts. How does "who controls the shelf" reshape consumer persuasion models?

ownership without possession

Subscriptions create psychological ownership without legal title. What happens to that ownership when the service ends?

androgyny in gendered categories

Androgynous branding works in neutral categories — but what about pickup trucks or luxury fragrances?
