I am a business academic specializing in marketing strategy, market-shaping, and consumer culture. My expertise is in the social and cultural dynamics of markets. As a business anthropologist, I use qualitative research such as ethnography, interviews, and social media listening to design consumer-led marketing strategies. My work encourages me to pay attention to culture and trends, embracing their complexity and contradictions.

I was born and raised in Mexico City and did my Doctorate (Ph.D.) in Finland. The dissertation explores how market research firms build actionable insights. My research unveiled how they distinguish the insights their clients implement by interviewing dozens of insights specialists in multiple countries. The dissertation has been published as academic papers in Marketing Theory, Industrial Marketing Management, and the International Journal of Market Research. The market research industry recognized this contribution, including me in ESOMAR's Insights250 list for 2022.

My academic work has taken me to business schools worldwide, including KEDGE Bordeaux in France, where I was an Assistant Professor of Marketing. Later, I joined the University of Auckland in New Zealand as a Lecturer and was promoted to Senior Lecturer.

Before entering academia, I was a consumer insights consultant to major companies in Latin America. Through my work, I advised organizations in diverse industries to identify and act upon consumer trends.

As an educator, I use my research and industry experience to teach university students courses like qualitative research, strategic branding, consumer culture, and user innovation. One of my interests is to develop teaching methods in close collaboration with insights agencies to help train the next generation of insights professionals. My teaching approach is designed with industry professionals considering the requirements of marketing agencies.

As a business academic, I have published over a dozen scholarly articles in well-respected, peer-reviewed scientific journals, including the Journal of Business Research, the Journal of Marketing & Public Policy, Marketing Theory, the European Journal of Marketing, and Industrial Marketing Management. My research interest lately has been in consumer engagement online with disinformation and conspiracy theories. For instance, my work studying flat-earth misinformation on YouTube; has been featured in news media.

  • My research integrates consumer culture and market shaping. I build upon my experience as a market researcher and marketing manager to investigate how firms construct consumer insights in ways that shape marketing strategy. My research focuses on the following three streams: (1) insights “as practice.” A stream in which I investigate how firms represent consumers in ways that textbooks fail to prescribe. (2) market-shaping. An empirical phenomenon in which an actor, usually a firm, fundamentally transforms its business landscape to its advantage. (3) Disinformation. I study the social and cultural dynamics of echo chambers in social media.

    As a snapshot of my academic career, I defended my dissertation at Hanken (Finland) in 2014. The dissertation resulted in three publications (ABS-3 UK ranking) – Two in Industrial Marketing Management and one in Marketing Theory. Together, they elaborate on how market research is performative, which means it profoundly influences how managers act, or in other words, how market research shapes the strategies managers consider viable.

    After my Ph.D., I joined Aalto University for a one-year postdoctoral contract on Consumer Culture. After the postdoc, I joined KEDGE Business School (Bordeaux, France) with my former co-supervisor, Professor Lisa Peñaloza, and the services researcher, Professor Jonas Holmqvist. The outcomes resulted in publications in ABS-3 publications –Journal of Business Research and the European Journal of Marketing. This work conceptualizes consumer tribes and experiential luxury.

    I joined the University of Auckland to participate in the market-shaping group led by Prof. Suvi Nenonen and Prof. Kaj Storbacka. My research explored how consumers shape markets. This effort resulted in seven publications in 2020. I will highlight two of them. The publication co-authored with Marian Makkar (RMIT, Australia) in the Journal of Business Research (ABS-3) explores consumer-led innovation, shaping multiple boardsport markets – e.g., kitesurfing, windsurfing, and stand-up paddling. The second collaboration with Prof. Hans Kjellberg (SSE, Sweden) in Marketing Theory (ABS-3) explores how cultural intermediaries exploit contradictions in popular culture to propose ‘feral’ segments.

    I am now part of the marketing faculty at Hanken School of Economics in Finland, my alma mater where I continue with my projects on the rhetorical analysis of disinformation and echo chambers.

  • My experience teaching in business schools is international. I have taught at Aalto University and Hanken School of Economics (Finland), Kedge Business School (France), Tec de Monterrey (Mexico), and the University of Auckland (New Zealand). I teach several types of business courses including contemporary marketing, qualitative business research methods, consumer culture, and brand management. My core competencies in teaching include cultural approaches to consumption, contemporary branding strategy, and consumer insights.

    Before my academic career, I worked as a consumer insights specialist for 5+ years in both a marketing agency and the client’s side. These managerial experiences provide me with a practical perspective that enhances my teaching. The focus is on interpreting multiple sources of consumer data to generate insights, which I define as actionable findings that can become the backbone of marketing strategy. As such, I emphasize the importance of managerial sensemaking in interpreting data, both qualitative and quantitative.

    Currently, I am teaching Consumer Behavior and Strategic Branding.

  • Before joining academia, I was a consumer insights specialist at a market research agency. Also, I was a marketing manager at the flagship airline in Mexico, Mexicana Airlines. Both roles offered a contrasting experience of how ‘consumer insights’ work for the client and agency.

    At Mexicana Airlines, my role required an understanding of how consumer insights apply strategically. By commissioning market research projects, commissioning them to agencies, and organizing their findings, I learned to interpret insights according to the firm’s capabilities. This dual experience (agency and client) informs my current research interests and teaching practice.
