I am a PhD candidate in Economics at Tilburg University, on the 2026–27 academic job market. My research is in macroeconomics, with a focus on production networks, macro-finance and information economics.
My job market paper quantifies how capacity constraints shape the propagation of sectoral shocks through the production network, and what they cost in the long run. In spring 2025 I visited Princeton University, hosted by Markus Brunnermeier. I expect to complete my PhD in May 2027.

Capacity Utilization in Production Networks
This paper quantifies how capacity constraints shape the propagation of sectoral shocks through the production network and their long-run cost. I build a dynamic production network model in which output is capped by a capacity proportional to capital, solve it as a graphon mean-field game and calibrate it to 63 US industries. Capacity constraints lower GDP per unit of capital by about 10 per cent, mostly through wedges paid along every production chain, and dampen the propagation of sectoral shocks to about three quarters of the unconstrained response, most for upstream and tight sectors.
