Assistant Program Director, Applied Economics, Johns Hopkins University

I develop methods for sequential decision making (dynamic programming, reinforcement learning and deep learning) and test them on the hardest instances I know: heterogeneous-agent economies in macroeconomics. I use these models to study the distribution of wealth and inequality, including how AI growth may impact households across the distribution. I am a core developer of Econ-ARK, the open-source toolkit for heterogeneous-agent models.
