WELCOME TO MY WEBSITE!

As a senior economist at the Belgian Competition Authority (Chief Economist Team), I provide economic analysis and quantitative evidence across a wide range of cases. I combine theoretical models and empirical methods to assess market dynamics and identify theories of harm in merger reviews and abuse of dominance investigations. In addition to case work, I contribute to long-term projects and actively engage in academic research. I have a keen interest in local market analyses, simulation techniques, merger screening tools, and sectoral studies.

In my own time, I make independent contributions on the tax avoidance practices of multinational enterprises — another area where firm strategy and public policy intersect and where the latter plays a key role in promoting fair and competitive markets. I have had the privilege to collaborate with impactful institutions such as the United Nations and the French Council of Economic Analysis. Furthermore, my research in corporate taxation has received special recognition from:

• the Belgian Fund for Scientific Research (Best PhD dissertation in all fields of science), 

• the United Nations (Best Research Work on International Investment and Development), and 

• the EU Tax Observatory (Young Researcher Award). 

I hold a PhD in Economics from Université Libre de Bruxelles, an MRes in Economics from Institut Polytechnique de Paris, and an Engineering degree in Statistics from ENSAE Paris. You can find more details about my background and current activities in my resume.
