Welcome

My research focuses on the macroeconomics of economic growth and technological development. Specifically, I study how economic growth is shaped by the dynamics of idea generation – particularly the recombination of existing ideas – and by financial access.

Here is my Curriculum Vitae. I am on the 2025-26 job market.
