We face complexity when there is no clear guideline for action. Today’s world is characterized by complexity. Diverging political interests, technological disruptions, and societal upheavals have created competing and divisive expectations about what we should be doing in our personal lives and in society. 

In my work, I tackle big questions to understand the complexity of markets and how people and organizations manage it.

For example, I answer questions such as how are public organizations responding to market pressures, how can organizations contribute to society while satisfying shareholder interests, and how are consumers reshaping markets.

My current research projects examine markets for coffee, tattoos, sneakers, fashion, music, transportation, microdosing, and education, as well as social projects in Africa, South America, and South East Asia. Based on my students' theses, I also am looking at digital influence and online influencers, and the acculturation of wealthy consumers.

My research has been published at the Journal of Retailing, Journal of Consumer Research, Journal of Marketing Research, and Journal of Marketing, where it has received distinctions such as most cited and most downloaded papers. It has been presented at the World Economic Forum, and the Association for Consumer Research, European Association for Consumer Research, Consumer Culture Theory, and American Marketing Association conferences. It has also been featured in media such as the National Post, Channel News Asia, CTV News, Global TV, CBC & Radio-Canada, Journal de Montreal, Les Affaires, and Le Devoir. 

I have received more than 750 000$ in funding from varied funding sources, such as the Social Science and Humanities Research Council and the Fonds Société et Culture. 

I am on the editorial review board of Journal of Consumer Research, Journal of Consumer Psychology, Journal of Advertising Research, and Recherche Appliquée en Marketing (RAM). I am also a mentor at academic conferences, a supervisor and committee member for master and doctoral students, and an instructor at JMSB.

Fundamentals of Sensation and Perception: PSYC 363

This course introduces the physiological and psychological mechanisms of Perception. Thorough treatment is given to questions of how information about the world is acquired through visual and auditory systems, and other modalities, that together is used with stored information to create an on-going mental representation of the world. Topics such as pitch perception, color vision, perception of movement, size and space perception, illusions, and perception of distance are covered.

Programming in Psychology: PSYC 725

This course covers basic and more advanced skills in programming in the context of experimental psychology and neuroscience. It focuses mainly on Python and R, as these two environments are open source and increasingly used by researchers and data science professionals. We review basic programming concepts and apply them directly to various forms of experimental designs using the PsychoPy building platform, from audio/visual stimuli presentation, subject responses, and interface with neurophysiological measurements. Data manipulation, analysis, and visualization are covered in R. Emphasis is placed on hands-on learning, developing the tools that students would eventually need in their academic endeavors. The goal is to shape a new generation of scientists that no longer rely on proprietary softwares, including for statistics.

Statistical analysis 2: PSYC 316

This course is designed to advance students' understanding of hypothesis testing and statistical inferences. From general linear models to mixed effects models, we highlight the limits of null-hypothesis significance testing and explore alternatives (Bayesian approaches, confidence intervals, effect size, meta-analyses). Students learn how to use programs such as JASP (https://jasp-stats.org/) and R (https://www.r-project.org/).
