Curriculum Vitae

Research Interests

Justin Sirignano's research lies at the intersection of machine learning, optimization, and stochastics. He is particularly interested in developing models, data-driven approaches, computational methods, and statistical tools for large interacting systems. Recent projects include fast large-scale optimization methods for loan portfolios and machine learning models for loan delinquency and prepayment. He won the 2014 SIAM Financial Mathematics and Engineering Conference Paper Prize. Justin Sirignano will be a Chapman Fellow at the Department of Mathematics, Imperial College for 2015-2016. In Fall 2016, he will join University of Illinois at Urbana-Champaign as an Assistant Professor (tenure track).
