YuJui Huang's research is focused on Mathematical Finance and the Mathematics for Machine Learning. It involves theories and techniques from stochastic analysis, stochastic control, optimal stopping, and viscosity solutions to fully nonlinear PDEs. Current projects involve financial planning involving healthcare spending, optimization under timeinconsistent behaviors, modeling federal student loans, and gradient flows for unsupervised learning.
