Professor Wang's research interests lie in the areas of actuarial science, quantitative risk management, mathematical finance, and mathematical statistics. His past and current research topics include (I) risk aggregation and risk measures; (II) extreme scenarios and model uncertainty; (III) negative dependence structures; (IV) stochastic order and risk comparison; (V) non-parametric high-dimensional data analysis; (VI) copulas and dependence modeling, and (VII) credit risk models.
