Portrait of Justin Doty

Justin Doty, Ph.D.

Senior Application Engineer, Econometric Modeling
MathWorks

I’m an economist and senior application engineer at MathWorks, where I help economists at central banks, government agencies, and financial institutions build and scale econometric models in MATLAB.

Before MathWorks, I was a research economist at the U.S. Census Bureau (2022–2026). There I developed differentially private methods for releasing business and survey data, including algorithms for heavy-tailed establishment-level data, and co-authored work published in the Journal of Privacy and Confidentiality.

My research is in econometrics and empirical industrial organization, with a focus on production function estimation under unobserved heterogeneity and measurement error. I received my Ph.D. in Economics from the University of Iowa in 2022, where I also taught econometrics and microeconomics.

If you’re working on econometric modeling in MATLAB, feel free to get in touch.
