I am a Ph.D. student in Economics at MIT. I am also a former Senior Research Analyst of the DSGE Team at the Federal Reserve Bank of New York. My research focuses on the determinants of business cycles, such as the role of coordination frictions, expectations, and the financial system in the propagation of macroeconomic shocks, as well as the capacity of monetary and macroprudential policies to address inefficient recessions. I investigate these problems using both theoretical and structural approaches. I also develop new computational methods to expand the range of problems macroeconomists can study, such as models with heterogeneous agents and/or nonlinearities.

Aside from research, I develop RiskAdjustedLinearizations.jl, which linearizes dynamic economic models around the stochastic steady state. I am a former lead developer of DSGE.jl, a Julia package for solving, estimating, and forecasting DSGE models, as well as SMC.jl, which implements sequential Monte Carlo (SMC) sampling for approximation of posterior distributions.
