I am an Assistant Professor at Universidad del Rosario School of Economics.
I received my Ph.D. in economics at the Paris School of Economics in September 2024 under the supervision of Agnès Bénassy-Quéré.
In summer 2023, I visited the London School of Economics Finance Department, sponsored by Liliana Varela.
I combine theory and microeconometrics to answer macro-financial questions. I am interested in understanding how, subject to regulatory and institutional environments, optimal and heterogeneous firm decisions impact macro aggregates. In particular, my research comprehends the unintended consequences of regulation and policy making on the (under)development of emerging markets' financial systems.
Before starting my Ph.D. I received an MA and a BA in Economics from Universidad de los Andes in Bogotá, Colombia.
