A list of selected research projects

A selection of research projects delivered over the past years at Decathlon, with a focus on the methodologies applied, my approach, and a bit of my background.

💬 Decathlon (2024 - 2026)

Introduction

My background

I am not a pure designer, which means I did not study Design at school. I have a background in Behavioral and Experimental Economics, which I found extremely useful when applying research methods in real projects.

I studied biases, heuristics, and how to apply rigorous methodologies to research studies. At first, I wanted to pursue a PhD, but that’s another story.

Today, I genuinely enjoy conducting research, interviewing customers, defining research protocols, and everything related to listening to users and understanding their behavior.

Research and tools

I joined Decathlon being positioned as 50% Product Designer and 50% User Researcher. This role allowed me to work on UX/UI projects while actively conducting a significant amount of research.

I was the only researcher in Italy, leading local research projects while progressively becoming involved in international initiatives.

I conducted research across multiple countries (France, UK, Spain and Netherlands) collaborating closely with researchers based in Amsterdam.

Well, actually, I think I ended up doing even more research than design… anyway, that's another story. 😅

In terms of tools, I regularly used:

  • UserTesting and similar platforms for usability studies

  • Contentsquare (heatmaps, journey analysis, session recordings)

  • Amplitude (basic data exploration and visualization)

  • Medallia for customer feedback analysis

  • Miro and Figjam during workshops, mapping activities and more.

Key projects

Here are some of the key strategic projects I worked on in Decathlon.

That's not all, this is around 5%. 🤓

Exploration and relevance of the homepage

Quantitative analysis

Quantitative analysis

Research goal

Understanding how customers perceive and navigate the homepage in order to improve relevance, clarity, and personalization.

My role

My role

I led this research project by defining the research protocol, script and conducting both moderated and unmoderated user tests.

I synthesized the findings, insights, and I flied to Amsterdam to present the project.

This research directly informed a 14-day design sprint focused on redesigning the homepage.

Interaction and behavior in search

Moderated user tests

Research goal

Research goal

Understanding how customers use the search bar, in which contexts, and how they formulate and select queries, in order to improve existing tools and the overall search experience.

My role

My role

I led this research project end to end. I worked closely with an analyst, observing and interpreting behavioral data extracted from analytics tools.

User tests were conducted and moderated across three countries: France, Italy, and the Netherlands.

I synthesized research insights and presented them to multiple PMs and designers across product teams in Amsterdam, influencing the strategy for Decathlon’s search and navigation menu.

Discovery research on Rental

Moderated user tests

Quantitative analysis

Quantitative analysis

Research goal

Research goal

Understanding the reasons behind a significant drop-off rate on the local rental website, in order to inform design decisions and identify improvement opportunities.

My role

My role

I led this project both as a Researcher and as a Designer. I conducted and moderated the user tests and mapped the end-to-end experience to define the new product roadmap.

This work enabled the team to map and plan a UX/UI redesign of the website: homepage, listing page, product page, and checkout.

This project was led by a Senior Researcher based in Amsterdam.

My role was to interview Italian customers and contribute to the synthesis of insights and actionable recommendations for the design team.

Conclusions

Conducting research has been fun for me, and I see myself as a Product Designer who conducts research, not a full-time researcher.

Research is hard and complex. It requires rigor, method, and skills developed over time. Knowing UX helps, but it does not make you a researcher.

Realizing this has been one of the most important learnings of my journey, and I am deeply grateful to the researchers based in Amsterdam and France who supported and mentored me during my years at Decathlon.
