Research Interests
Justin Sirignano's research lies at the intersection of machine
learning, optimization, and stochastics. He is particularly interested
in developing machine learning models, computational methods, and
statistical tools for large systems (one example being financial systems). Recent projects
include fast largescale 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 20152016. In Fall
2016, he will join University of Illinois at UrbanaChampaign as an
Assistant Professor (tenure track).
