My research employs a mixed-methods approach–ranging from traditional legal analysis to causal empirical projects—to understand how governments influence markets and, in turn, how markets influence governments. I focus on two complementary areas: (i) antitrust and economic policy, emphasizing the political, economic, and legal determinants of enforcement actions and regulatory change; and (ii) the governance of digital markets, where I focus on designing policies for competition, data privacy, content moderation, and other areas to enable them to better achieve their stated goals. By employing a combination of interdisciplinary and comparative methods, I try to understand how changes in legal regimes and enforcement priorities influence economic incentives and the on-the-ground behavior of market agents and regulators.

I hold a J.S.D. and an LL.M. from the University of Chicago Law School, a M.Econ from INSPER, and an LL.B. from FGV Direito São Paulo. Before joining academia, I worked as an antitrust and technology regulation lawyer in São Paulo and Brussels. I am also a Fellow at the Stigler Center at the University of Chicago Booth School of Business, a research affiliate at the ETH Zurich Center for Law & Economics, and an Associate Editor of the Journal of Competition Law and Economics.

My work has been published in leading law and peer-reviewed journals. It has been mentioned by The Economist, Politico, The New York Times, the Washington Post, Bloomberg, Fox Business, and the 2020 Economic Report of the President (among others).

Disclosure Statement:

According to the ASCOLA Declaration of Ethics and the AEA Disclosure Policy, I declare that over the past five years, I:

– Received compensation from my academic employers: Georgetown University, ETH Zurich, and the University of Chicago

– Received a research grant from CERRE, a Brussels Think Tank, to engage in the research that led to the report on Access to Data and Algorithms: for an effective DMA and DSA Implementation. This report was jointly supported by the British OFCOM, the French ARCOM, Google, Booking.com, and TikTok. I had no engagement with these parties other than through CERRE. We retained complete discretion in writing the report, and we conditioned the writing of the report on receiving the support of at least two regulators to ensure our independence.
