Jason M. Klusowski

Biography

Jason M. Klusowski is an Assistant Professor in the Department of Operations Research & Financial Engineering (ORFE) at Princeton University, where he is also a Participating Faculty in the Center for Statistics and Machine Learning (CSML). His research interests broadly span statistical machine learning for complex, large-scale models, focusing on the trade-offs between interpretability, statistical accuracy, and computational feasibility. He works on topics such as transformers (encoding and decoding of sequence models), decision trees and ensemble learning (CART, random forests, stacking), neural networks (approximation theory and statistical properties), gradient-based optimization (ADAM, SGD), and the large limit behavior of statistical models (Lasso, Slope).

Prior to joining Princeton, Jason was an Assistant Professor in the Department of Statistics at Rutgers University, New Brunswick. He completed his Ph.D. in Statistics and Data Science at Yale University in 2018 under the supervision of Andrew Barron. From 2017 to 2018, he was a visiting graduate student in the Statistics Department at The Wharton School, University of Pennsylvania.

Starting in January 2025, Jason will serve on the editorial board of Bernoulli—Journal of the Bernoulli Society. His research is supported by NSF CAREER DMS-2239448 (PI) and previously by NSF DMS-2054808 (PI) and TRIPODS DATA-INSPIRE Institute CCF-1934924 (Senior Personnel).

Jason grew up in the heart of the Canadian Prairies, in Winnipeg, Manitoba. His spouse is an Assistant Professor of Marketing at Yale University.
